Answer 1

a) Si : [Ne] 3s2 3p2
No. of unpaire electrons = 2
b) Zn : [Ar] 4s2 3d10
No. of unpaire electrons = 0
c) Zr : [Kr]4d2,5s2
No. of unpaire electrons = 2
d) Sn : [Kr]4d10,5s2 5p2
No. of unpaire electrons = 2
e) Ba: [Xe]6s2
No. of unpaire electrons = 0
f) Tl : [Xe]4f14, 5d10,6s2 6p1
No. of unpaire electrons = 1
