hello,
i have a question related to metallic bonding.
As far as i know, valence band is defined as the highest filled level in the band and conductionband as the 1st unfilled level. So, if I have 100 Li, we will have 100 orbitals which form a band. Since we have 100electrones, 50 pairs, so we occupy half of the band right? then... valence band would be level 50 and conduction band 51? or is it more like: the all the filled leves form de valence band and all the empty ones the conduction band?Also, for a transition metal for example, what would the valence bond be for eg Cr? i mean, how do you define valence band? does it always have to be full?
