If FCC and HCP are the ones with the highest atomic packing factor, why would there be metals with BCC structures?
Not magnetic characteristics, but probably electron configuration.So the reason for the existence of BCC metals has to do with magnetic characteristics? Ok that is definitely a good thing to think about. Unfortunately I don't know much about those. In any case, thanks for showing me this.
Actually the alkali metals (group1) and barium and radium(group2) also have a BCC structure.It seems that all the metals that have a bcc structure are transition metals.
Correct.Actually the alkali metals (group1) and barium and radium(group2) also have a BCC structure.
I echo Vanadium's comment and further ask is the packing difference (68 as opposed to 74%) so very large?
