Question

Sodium is more metallic than nitrogen why

Answer 1

Explanation:

because sodium is element of Group-1 and thus it's easy for sodium to lose electron that nitrogen which is element of group-15

And allowing Sodium to show more metallic (i.e., electropositive character) properties than nitrogen

more explanation lies in electronic configuration

Sodium has Atomic number=11

Na= 1s2 2s2 2p6 3s1

thus one electron in outermost shell

while in Nitrogen

Atomic number=7

N= 1s2 2s2 3p3

thus three electrons in outermost shell

now you can easily guess for whom it's easier to loose electron
