This is neat. I wonder why my teachers back in high school and college didn't teach this stuff. Some of my teachers were decent but for some reason metals were not covered this well.
I was taught that when the interstices of metal solids are filled by small mass atoms like carbon that the overall density decreases not increases as you said, since adding the atoms in those holes increases the overall volume
you r such a great teacher Mr.Anderson! thank u for all ur videos! juz one thing , how is the sea of electrons actually forming.. is it juz tht metals r electropositive n so the outermost electrons juz break off?
Most metals tend to form cations, since they usually have some extra electrons and they want to get rid of them. So when a metallic bond is formed, these extra electron turn into free electrons and each metallic atom has these extra electrons so when the bond is formed these extra electrons turn into free electrons and a sea of free electrons is formed.
I really struggle to understand the idea of an electron sea model, what is it exactly ? How is it possible ? I would like something like a really detailled explanation on that. Thank you for posting all these great videos !

I can't believe how much learned and understood in just 4 minutes.

i was taught that too. sorry this comment was like 2 years ago lol but thanks
A time saving video! So much in just 4 min :D

Carbon in an iron lattice prevents dislocations from propagating which relieve stress and cause the metal to bend rather than break.
Thank you so much for making chemistry videos!
you a soy boy fr
Very good explanation at all!......only positive ions form the structure of metal ??positive ions aren't stable enough!....aren't they??
I really like your videos, they (you) help me a lot!
nice
Sir why metals are shiny? As these electrons are free and delocalized so how they move to higher energy levels.
Thanks
Really helpful =)
yes
