Answer

(a-q,s);(b-p,r)(c-q);(d-p)

Explanation

`Fe^(2+)rarr1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(6)`
`rArr`
No. of exchanges `= (5!)/(3!2!) = 10`
`Mn^(4+) rarr 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(3)`
`rArr S.M. =2|(3)/(2)|+1=4`
`Zn^(2+) rarr 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)`
`rArr mu = 0`
`Na^(+) rarr 1s^(2)2s^(2)2p^(6)`
`rArr mu =0`
last `e^(-) rArr n=2, l=1, m=+1,-1,0,s=+-(1)/(2)`
