Give the decreasing order of magnetic moment of the following:
(a) `Ca` , (b) `Al` , ( c) `N`, (d) `O`

Text Solution

Verified by Experts

(a) Electronic configuration of `Ca = 4s^(2),n = 0, mu = 0`.
(b) Electronic configuration of `Al=3s^(2) 3p^(1),n=1`, `mu = sqrt(3)`.
(c ) Electronic configuration of `N = 2s^(2) 2p^(3),n = 3, mu = sqrt(3)`.
(d) Electronic configuration of `O = 2s^(2) 2p^(4),n = 2, mu = sqrt(8)`

Hence, the decreasing order of magnetic moment or paramagnetic is
`N gt O Al gt Ca`
