I'm not pleased with his explanation at all. What's an alpha particle? How did they know they were smaller than an atom? How did they shoot particles smaller than atoms when they didn't know what an atom was?
Rutherford knew very little about alpha particles. He knew they were very small (much smaller than an atom), and he knew they were positively charged. But since he hadn't yet discovered the nucleus, he certainly didn't know that they were actually Helium nuclei!
@@sazokuotsutsuki8848 sorry for my english btw Alpha particles (or alpha rays) are the result of a radioactive activity which is radium turning to radon for example Since radium has a very large (A), the nucleous is unstable and thus in its way to be more stable, it loses 4 nucleons and shoots them as a form of alpha particles (rays) which are 2 protons and 2 neutrons which are technically a helium nucleus Hope that helped but you can google it or search about it on youtube
All great questions! 1) Alpha particles don't actually have to hit a nucleus in order to be moved, because the charges repel 2) If alpha particles were negatively charged, they might stick to the nucleus instead of be repelled by it. 3) I'm sure alpha particles hit electrons, but electrons are so tiny compared to the size of an alpha particle, they don't do anything, it's like a bullet hitting a piece of dust.
Great question! In order to get repelled by the protons, the alpha particles have to get super close to them (almost touching). And since nuclei are so tiny compared to the atom as a whole, it's really easy for the alpha particle to go through empty space in the atom without coming anywhere near the nucleus.
Thanks! You know, Ernest Rutherford was from New Zealand. And you should watch my video called "Why Does Everyone Hate Science?" (it's less than a minute long), because there's a subtle New Zealand shout-out in that!
I've been watching your videos lately and I just want to thank you so much! I admit that I'm a pretty slow learner, and because of that, I need to take note of every LITTLE DETAIL (it can get quite annoying) just for me to understand a particular lesson. Your conciseness helps out so much and I love how you are able to hold my attention for as long as your videos are! I just want you to know that you are truly amazing and I hope you continue to help other people who are in the same spot as me :) THANK YOU!
Alpha particles are made of only two protons and two neutrons. They are NOT complete Helium atoms; if you want to be precise, they are only the nucleli of Helium atoms, but they don't have any electrons. The nucleus of an atom is tiny compared to the amount of space that a whole atom with electrons takes up, so it's perfectly fair to call an Alpha particle "much smaller than atom," because it is. It's only a tiny piece of an atom.
I wish my country had this kind of teacher but our country does not promote talent but they want 90 % in every subject U ar the best teacher may Allah bless u
I've really been enjoying these videos. For the critics, you are entitled to your opinions. However, Tyler has put a lot of effort into his videos, and you can't argue with that. Thank you Tyler.
Thank you Tyler. The mark of a good teacher is their ability to convey information in ways that are understood by those being instructed. So sick of teachers showing off how smart they are by talking over students. You actually teach. Thank you for your brain and your humility.
No words!! Even if i use each and every word of every language of this world to thank u and praise ur hardwork, it wouldnt be enough! The way you expalined is beyond any word!! May God help you in ur work!!! and wish God make me a person like you who uses all his strenght and intelligence in helping people!!! No words!! speechless!!
Just want to say that I appreciate your videos so much! I've recently started an intro to chemistry course at uni and have been really struggling to get my head around this topic, the way you are explaining things makes it so much easier to understand! Thank You!!
You are literally the only person I learn from on RUclips. Clear explanations attacking every point with laser beam precision. It would be a dream come true if u had the time to make a video on a topic practically my whole class is having trouble with: Lattice Energy (: Thank u for all u have done for us! (: God bless u
Thank you sooooo MUCH! Chemistry has always been my thing but you are making it a lot more better. I am a proud supporter of your youtube videos. Thanks again!!
I'm a science teacher and your videos are of huge help to me and to my students for independent learning sessions. Thank you so much. God bless you and more power.

Tyler Dewitt, you're the best Chemistry RUclipsr ever! I Liked your videos before I even finish them just because I already know it's gonna be great. Thank YOU for the awesome videos.
Man no actually sir I just got blown away by your details and explanations it's just amazing I was able to understand each and every thing tat u taught one of the most informative and helpful video I have ever seen
you are literally saving my academic life I am not even kidding, the videos you make help me with so much stuff we do in physics (i am aware that this is chemistry but there seem to be some overlappings) thank you from the bottom of my heart
Thank you so much! I'm sitting NCEA Level 2 Physics (National Certificate of Educational Achievement) (New Zealand) and I was so confused, until now, Thank-you!
Tyler, I also am a teacher. I hope I will be able to teach like or better than you in the future. You are a professional role model and an inspiration too. Thanks for choosing the teaching way and thanks for always been there.
Ernest Ruthestford (1911) 1. What experiment did he do? Take a piece of gold foil and place it in the center of an almosted closed circle. Shoot alpha particels(smaller than an atom, positively charged) at it. 2. What happens in this experiment? They see a flash on the metal. The place of the flashes don't always go straight. Sometimes they veer off to the side and even flash back to the alpha particle emitter. 3. Conclusion -Most of atoms is empty space -There is someting in the center, a.k.a the Nucleus -There is something attracting the alpha particel to veer off, a.k.a. the electron. -They soon realized that the electron is probably not saying still
thank god for these videos!. i just came back from holidays (waged a week of uni) and come back with a chem exam on that week!. doing a all nighter so my brain can absorb this material. THANK YOU THANK YOU THANK YOU!!!!!!!!!! 100% brain energy
what are you man awesome i have never seen someone teaching like the way you do i am speechless you are doing amazing work keep it up you are the best teacher i have seen so far all over the world
Well done, Tyler. You are an efficacious & inspiring teacher. I grew up watching Carl Sagans' "Cosmos." He both entertained and inspired, as you do. You remind me of him. Brilliant work!!!
totally saved me from school... i cant understand much when im in school but this video made me understand what my teacger said more! really wish there is a professor like you if i go to college... soo goos at explaining!
I love your work you really help me out a lot because my teachers never explain things like this, "or say zooom" , they just give out a pamphlet with drawing and explain very little, thank you for your work, and never stop no matter what , thanks
Simply outstanding. You get a gold star for teaching this. It clears up a lot of questions I had about how the model of the atom as we know it today evolved over time. Simple, but accurate. God bless you, man!!!
You are ridiculously Good. Would be great if you enlist your lectures Topic wise in separate playlists... like Physical Chemistry, Organic, Inorganic and Basic Chemistry all in separate playlists.
Tyler I really enjoyed the way that you want to teach us some chemestry discoveries. I am french and actually I think that I have already understood all the points of your lesson. Thank you so much for your work, now it will be esier for me to learn the atomic model of Rutherford
I don't understand where the alpha particles came from. Didn't they just barely discover that atoms weren't the smallest particle (thanks to the discovery of the electron)
Yeah I'd like to know as well. If atom was the smallest in their era, how could they come to conclusion that alpha particles were positively charged and moreover that these were not atoms? coz how would they know that they were not shooting the gold foil atoms with other atoms(alpha particles atoms)?
For anyone confused as to why Rutherford expected the *positively-charged* alpha particles to pass without resistance through the huge volume of *positively-charged* matter constituting the atom in the Plum-Pudding Model: it's because Rutherford perceived Alpha particles as being comparable to a rifle, and the *positively-charged* matter comparable to as a tissue.
Thank you so much, for making me understand as my English is a secondary language. I got a lot of help from you. not only that I didn't have a base in chemistry also.
Thank. You. So. Much. I really needed to know these things for school, I have an assignment due tomorrow and feeling really good about it after watching this, thank you so much.
Thank you so much. I finally get the concept of his experiment. It's really hard to understand this concept by simply reading what's written in the book. Terminologies are too hard to understand making it hard for me to imagine it.

This was explained way better than a teacher or a textbook. Thank you very much.
@@user-if1de8pt2j Yeah. And it's true.
Latricia Hayles not even my fricking Cambridge trxt book could explain this better than him
Hi so it has been 5 years since you studied this lesson , i just wanted to ask if it was helpful with ur life :)
I'm not pleased with his explanation at all. What's an alpha particle? How did they know they were smaller than an atom? How did they shoot particles smaller than atoms when they didn't know what an atom was?
I literally came here straight from my Chemistry: Atoms First textbook in order to better understand what I was reading.
Rutherford knew very little about alpha particles. He knew they were very small (much smaller than an atom), and he knew they were positively charged. But since he hadn't yet discovered the nucleus, he certainly didn't know that they were actually Helium nuclei!
Ho-
How can you separate it's electrons from it when it doesn't even react to anything...
@@sazokuotsutsuki8848 sorry for my english btw
Alpha particles (or alpha rays) are the result of a radioactive activity which is radium turning to radon for example
Since radium has a very large (A), the nucleous is unstable and thus in its way to be more stable, it loses 4 nucleons and shoots them as a form of alpha particles (rays) which are 2 protons and 2 neutrons which are technically a helium nucleus
Hope that helped but you can google it or search about it on youtube
when you realize you are already using something you are going to discover.ha lol
aren't helium nuclei supposed to be in a helium atom!! what are they doing outside it and did they come outside their area??
Do you have a video on mass spectrometry?
If no, can you please create one on that.
I have a hard time understanding that topic
All great questions! 1) Alpha particles don't actually have to hit a nucleus in order to be moved, because the charges repel 2) If alpha particles were negatively charged, they might stick to the nucleus instead of be repelled by it. 3) I'm sure alpha particles hit electrons, but electrons are so tiny compared to the size of an alpha particle, they don't do anything, it's like a bullet hitting a piece of dust.
OO
OH the third one answered my question damn ur really good at this
I got it
Thanks!
This has cleared up my thoughts on the absence of the Electron’s impact on this experience! You are brilliant sir!
Great question! In order to get repelled by the protons, the alpha particles have to get super close to them (almost touching). And since nuclei are so tiny compared to the atom as a whole, it's really easy for the alpha particle to go through empty space in the atom without coming anywhere near the nucleus.
Yours Explaination is really fabulous,👍👍👍👌👌👌
I have question why does the nucleus not disintegrate in spite of repulsion among the proton??
Thanks! You know, Ernest Rutherford was from New Zealand. And you should watch my video called "Why Does Everyone Hate Science?" (it's less than a minute long), because there's a subtle New Zealand shout-out in that!
Lol, yeah, 7 years, been a long time dude.
The world needs teachers like him, he is truly the best.
No teacher would shout "Bam Bam Bam" in the middle of the class😂Hats off to you💯
