Metallic Bonding

021 - Metallic Bonding

In this video Paul Andersen explains how metallic bonding structure creates the different properties of metals. The electron sea model explains how the positive nuclei are locked into a negative sea of delocalized electrons. This sharing of electrons creates metals that are good conductors, malleable, ductile and non-volatile. A shell model can be used to explain certain properties of metals (like melting point).

No problem. I'm happy to hear that you enjoy them.

This was exactly, exactly what i was missing to clear up a lot of unease I felt understanding electricity and magnetism. I cant believe i don't remember this being explained to me in high school chemistry. Thanks.

[henney]

thank you so much! you are doing such a great cause helping out students with bad professors! we need more teachers like you!

[michellequinn]

Thanks so much. Your explanations and graphics are so helpful!

[sophiejain]

I'm pretty sure this yt channel is the reason I don't fail science. TY so much :)

[jayladark]

Great video! Super helpful. I love the Khan Academy videos too but sometimes they just ramble way too much. This was straight to the point and so much easier to understand! Thank You!

He's been mistaken at 4:52 by saying MAGNESIUM instead of MANGANESE, Please put the correction note in the video. Thanks.

I think metallic bonding is the hardest concept to understand between the bonding of the atoms. I still don’t get how the negatively charged electrons from the valence shell ( sea of electrons) attract to the the atom. Is it attracted to the protons in the nucleus?

at 5:15, isnt Cu suppose to be 4s1 3d10? should that make it more stable hence why it has such a low melting point?

Bozeman Science deserves more views! Great high quality videos, cheers.

I now know where to look for an easy to understand chemistry guide, thank you

This is digressing a bit from metallic bonding, but s & p valence electrons undergo MO hybridisation. Is it a property of d & f valence electrons that they do NOT hybridise, but behave differently, resulting in "electron seas" for neutral metals and the formation of ionic bonds that also react with react with ligands? Can it be said that this always applies?

[angelatsai]

Thx that helped me a lot to study for my science

[sharonsng]

sorry could someone explain why the more stable ones e.g Manganese has a lower melting point? Shouldn't it require more energy thus more heat/ higher temperature for it to melt

[afroninjawithswag]

Clear explanation, thanks for the info.

Very helpful video!
Though, I would like to point out a mistake.
At 4:54, you said Magnesium instead of Manganese.

[onespace]

That was definitely helpful with such visualisation.

I can't help but wonder with all those electrons moving around if electrically induced magnetism has an effect on the physical properties of metallic atoms.

Thankyou soo much!! It was really helpful since i have an exam tomorrow :) 

[Doomzdayxx]

Thankyou so much for the work that you put in to your videos!
