I love this guys explanations so much! He goes slowly and speaks clearly. I also appreciate how he gives a LOT of examples. He is a MUST watch for all chem students. Thanks for helping me pass chem! Can't wait to be done after the final!
Most professors are arrogant they are hired based on their qualifications and their main focus is their research meanwhile teaching requires communication skills along with dedication.
You are the best professor. I use to hate chemistry because it is very confusing but you made it so easier that now it became my favorite subject. You saved my life! Thank you. I scored 100 on exam because of watching your video.
You are the best Chemistry Tutor on RUclips you make everything seem easier and understandable. I will always be honored to watch your videos ,you deserve my versity fees👏😩
I literally fell in love, this was explained so clearly, I'm so glad I found his channel, if you really feel like the chemistry isn't sticking, watch him, he explains it without using convoluted words all while using the definitions amazing. I have hope that I'll catch up to my understanding of chemistry 1 & 2 before my next year at college, seriously thank you for doing this for free 🙏🙏🙏🙏
the introduction was crazy, "How can Hydrogen (Atomic Mass = 1) be bigger than Helium (Atomic Mass = 4) when Helium is more mass-ive than Hydrogen." I was glued to the screen after than statement.
Notes (random): Atomic Radii- As you go down a group, the atom adds more energy levels, therefore increasing the atomic radius. According to Coulomb’s law, distance and force of attraction are inversely related. If you increase the distance of the valence electrons to the nucleus, the pull the nucleus has on the valence electrons is reduced. The valence electrons are also repelled by the shielding electrons. Ionic Radii- Cations have less electrons, therefore less electron shells. This makes them significantly smaller than the parent ion. As the size of charge increases, the size of the atom decreases. Anions are larger than the parent atom because there are more electrons. This increases the repulsion, therefore increasing the ionic radius. As you go down a group, the number of electron shells increases, therefore the size of the ion increases. For isoelectronic ions, the ion with the higher amount of protons has the lower ionic radius. As you increase the number of protons in a radius, the FOA between the nucleus and the electrons increases. This pulls the electrons closer together, reducing the size of the atom. Isoelectronic- same number of protons and same electron configurations Electronegativity: -The ability of an atom to attract an electron towards itself -Florine is the most electronegative element (4.0). -Electronegativity increases as you go up a group and towards the right of a period. -Non-metals are more electronegative than metals (higher electronegativities) -Ionization Energy: The ability to remove an electron from a atom. Metals tend to have a lower ionization energy compared to non-metals since they like to loose electrons (become cations). On the other hand, non-metals like to gain electrons (become anions) so it’s harder to take one away. -ionization energy increases as you travel left to right. The electrons stay on the same energy level, however, more protons are being added. This increases the effective nuclear charge, which means the nucleus would have a harder pull on each individual electron. This means more energy would be required to remove a single electron. -As you go down a group, the ionization energy decreases because the distance between the valence electrons and the nucleus is increased. Electron Affinity (kj)- The energy change that occurs after a neutral atom gains an electron

Professor Organic Chemistry Tutor, thank you for a massive analysis into Ionization Energy , Electron Affinity, Atomic Radius, Ionic Radii, Electronegativity and Metallic Character in AP/General Chemistry. Practice Problems, Visualization, and Drawing the Electron Shells of an element increases my knowledge and deep understanding of the material. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.
This video was very much so helpful, I have a test coming up , I was so lost & confused before watching this video, now I am confident In taking my test & excited!!
Thank you so much... I took me three days because of my laziness but I am so grateful this was there. I have exam in a week and I am slowly covering up because of you.
Thank u soo much for taking your time out to make this video, I fell asleep in my chemistry zoom class so this really helps. You literally explain the whole topic.
Taking organic chemistry this summer and my professor made me so confused about how the atom works and we have to think outside the box on its fundamental thinking on how and why atom reacts certain ways for protons and the whole thing with the distance and force and number of electrons and I was just not getting it. My proof was too vague and make me have a headache. I thank you for this video and I was able to take notes and understand the concept and the explanation is the best. Very helpful indeed! I'll be reviewing much of my class materials by your videos. :D
Thanks for your easy to understand videos. Periodicity one of the topics I have had difficulties with. Your video is highly appreciated. One of the standardized tests asked the student to predict which element on Periodic Table is likely to be a liquid. Which periodic characteristic is being tested by this question?
Thanks a million JG! I don’t know what I would have done without your video. You cover topics end to end. PLEASE TEACH TO CALCULATE PH WITHOUT USING THE CALCULATOR. PLEASE TEACH MORE ABOUT QUICK MATH DURING TESTS THAT DOES NOT ALLOW CALCULATOR IN CHEMISTRY 🙏🙏🙏🙏🙏
Lo Tavares good question. check out this little secret to the periodic trend that will help clear things up twitter.com/itsdewon/status/815968771726831617?s=09
I have no idea to this video it help me to understand the topic. You are very brilliant men. I asked you to do more video in more topics. Thank you very much.
Well done.., but at around 31:00-32:00 u messed things up about electro negativity.....sayin it decreases to the right and increases left wards....but still nice work, learnt so many things from the video...thank u 👍
@@TheToxicMegacolon I'm really struggling in genchem too. But his videos are so helpful, so hopefully between them, Khanacademy, and doing practice problems, I won't fail.
Sir, in have really benefited from teachings since I came across your notes on U tube, but sir I really have problem with qualitative analysis in chemistry. I don't know how to identify cation and anion . I really Want you help me out. Thank you best teacher in the world.
Sir, thank you so much to releasing this vedio , this vedio cleared all my problems in atomic trends and greatly helped me on getting good marks in the unit test
Love your videos , but you should really turn up your recording volume. We can always turn it down if its too loud but there is only so far we can turn things up. Im going deaf and its tough to hear without being able to turn up the volume.
this video is so helpful, however it will be better if the speaker/teacher will speak in a more energetic & loud voice so that we'll understand better and enjoy it at the same time. Thank you for this video, TOC! 😊💗
Thank you so much for this video, I really learned a lot. But I do have a clarification in 31:13, about the electronegativity trend when the arrow goes to the right, isn't increasing? I was just confused because in the first part in 27:18 you said that it also increases. Thank you.
nope. you are thinking of about the electronegativity. the atoms are larger of the metal ones. there is not a lot of elements fighting attracton n repulsion, while the others do so there is more compression
i'm a little late but, why is the effect of going up on the groups gratter than the effect of going right on a period when it comes to electronegativity?

It's interesting that one guy with a genuine desire to explain this stuff to people does more good than thousands of "professors" put together.
@MRK.EDITZ. tens of thousands
No, MILLIONS.

This guy has changed my entire prospective about chemistry..I used to struggle with chemistry and hated it but now it's my favorite subject

31:30 he messed up there, flipped left and right
cool guy yeah
Yes
Video has never been so helpful tysm 😿😿😿

feeling satisfied by ur explanation thanks and be blessed
Thanks man one video - one chapter completed good job
That was a helpful video Thumbs Up😊😊
What imagination... the one who imagined the concept is really a genius...
