Question

Out of lithium and k which will have stronger metallic character and why

Answer 1

K has a stronger metallic character as it can lose it's valence electron more easily than Li. This is because K is larger than Li, by screening constant, it is very easy to lose the valence 1 electron

Answer 2

k has stronger metallic character than lithium because as we go down the group in a periodic table the metallic character increases.
