*The color-coded periodic table of elements at room temperature and 1 atmosphere is intended to give a rough visual understanding. I could not locate a peer-reviewed source broad enough to be useful, so I colored this table based on the comparison of two sources that complied data. These agreed on the majority of elements. Some disagreements could be understood (such as one source counting elements with double-HCP structure as HCP and labeling certain elements as having a single structure at room temperature) but table is not an authoritative source.

oh my god this video is the medicine to all engineering caused stress disorders
You explained what my professor could not explain in 3 lectures. I really appreciate it ❤👏👏
What my professor was unable to make me understand in 3 long lectures, you just did that in 20 minutes💥
Please make more of these videos, this does such a better job of explaining the topic compared to any other resource I've used! I wish there was more for similar topics
Wow, such a nice video. Perfect explanation and you said all these in a way like you feel the difficulties students undergoes. I hope you will continue making videos
This is by far the best video on crystalline solids on RUclips!
thank you! I had a really hard time figuring out the coordination numbers of the different crystal structures. Seeing it just as the number of atoms an atom in a crystal touches makes it so simple!
PLEASE make more videos. Your way of teaching is fantastic.
Just wanted to say great video, there's a clear passion and understanding for the subject here. I've watched consumed many materials on this topic and they always felt impersonal and technical. But this video strikes a great balance between informative and comedic, drawings look good too and are easy to understand. Love it.
SO this saved my life. Thank you for such an awesome informative video!
Hopefully you'll make more videos in the future because this was super helpful!
Absolutely incredible. Wow what a video
Best video around!! I love it
Thanks for the awesome video! My inorganic chem final is tomorrow and I must say this is the best video out there reviewing topic!
i want to know why i understand any video in youtube better than my professor
First time hearing a metallurgical engineer from youtube. Yay fellow metallurgical engineer
I feel the same way!
Oh my goodness, this helps me a lot! Thank you very much for this video!
Amazing video! Unit cells are the building blocks of solids, and this video enabled me to understand it far more than the textbook did! Everything was super clear and great visuals. Would love to see more videos!
I love you for producing this amazing video
Thanks, it really cleared things out.
You naild it sir🫡
Please make more videos🙏
thanks bro that lecture was really help full for understanding the structure of atom
WONDERFUL 😊🙏🙏 AM IMPRESSED, WHERE CAN I GET MORE OF THESE VIDEOS?
Ok um.....I dont know why the actual heck you have such less subscribers but this was an extremely fun fun way of teaching and I didnt understand it much how hard I tried so thanks alot
this was so helpful thank you!
Tremendous effort and clear as day explanation 👏 ❤
P.s. Can We connect on LinkedIn please?
ty so much for your explanation it really helped me
Amazing video
Amazing ❤
oh my god did this random man from youtube just save me frustration from my inorganic class? thank you for your service 🫡
thankk u ,great explanation
woww so good thank youu so much for the help today is my solid state examination
Thanks alot
this is superb ❤️❤️
ty so much!
THANKS MAN
Thanks for that art
no more?😢😢
Whye there are only two more videos in your channel....😢
Thanks as a science student from India this was really very helpful but there are also some topics left like c, Location of voids , radius ratio , defects ...hope u will make video .m
One of these is in the works right now. Sorry for the delay 😅 I wasn’t going to originally make this a series but I’ve been inspired to do so.
Just don't understand at 10:58 how you got that √3a
Let me see if I can help. Draw a right triangle where the diagonal in question is the hypotenuse. Label it x as the length we are solving for. The other arms of the triangle are known: "a" for height and "√a" for the square diagonal. Solve using the pythagorean theorem a^2 + b^2 = c^2. You fill find that a^2 +2a^2 =x^2 which then simplies to √(3a^2)=x. Thus, x=√3a.
At 16:22 it should say "FCC and HCP begin with the same base layer" not "FCC and BCC”
Great video!
❤
By the way you are a very excellent person ❤🎉
Wow,nice and clear explanation, I should have paid my college fees to you for tuition instead
Thank you! It’s comments like this that help light a fire under me to continue this series (the next of which I’m happy to say is in the works!)
@@collinandersen3369 This was as excellently educational and entertaining. Like on minutePhysics levels. 10/10! I look forward to more videos. :D
Please make more videos
Chemists: thinking they can run away from mathematics
Crystallography:
More videos sir
I’m happy to say the next one is close to being done
The worst part is having to take a materials science class as an industrial engineer for ABET accreditation reasons :(
4:30 is advice beyond any field of study
Why did i follow this and then want and begin to take notes ... play WTF am I supposed to be some sort of material scientists why am I taking interest in this ADHD plus booze got me whildin right now
can't see the forest staring at the tree. materialistic views. can't count everything. if you feel you can, count the love for your children or parents who has more. i wont believe you unless you can show me. if you cant explain it to a child you dont understand it. registration and comprehension are incommensurable.
no atom has ever been recorded in history. can't use electricity to view something then call it a atom 😂 everything has a frequency for good reason
no talk of quarks or muons and nuons 😂 wheres quantum jibber jabber in all this 😂 the masses have much to learn. Long Live The Æther and all its modalities.
I have mid exam tomorrow thx for helping me 🤍
Good luck on that test!
why there'are only two videosss 🥹
