Solution

The correct option is A (a) p, q, s; (b) r, s; (c) q, r; (d) p, q
Ni(28)1s2 2s2 2p6 3s2 3p6 3d8 4s2

Ni2+3d8 4s0

Number of unpaired electron in Ni2+=2
m - 0 present in all orbitals
2 + 2 + 2 + 2 + 2 + 2 + 1 = 13 (min)
Atom is paramagnetic.
It is transition element.
(b)
K(19)1s2 2s2 2p6 3s2 3p6 4s1

K2+3p5

m = 0
Number of unpaired electron in K2+=1
m = 0 present in all orbitals
2 + 2 + 2 + 2 + 2 + 1 = 11 (min)
Atom is paramagnetic
It is not transition element
(c)
Mn(25)1s2 2s2 2p6 3s2 3p6 4s2 3d5Mn2+ 3d5
m = 2 + 2 + 2 + 2 + 2 + 2 + 1 = 13
(Transition element)
Number of unpaired electron in Mn2+ = 5
m = 0 present in all orbitals
2 + 2 + 2 + 2 + 2 + 2 + 1 = 13 (min)
Atom is paramagnetic.
It is transition element.
(d)
Pd1s2 2s2 2p6 3s2 3p6 4s2 3d10Pd2+ 4d6 5s2 4d8
Number of unpaired electron in Pd2+ = 2
m = 0 present in all orbitals
m = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 1 = 19
Atom is diamagnetic.
It is transition element.
