a) `1s^(2) 2s^(2) 2p^(3) implies `

(b) `1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(2) implies Z = 20`
c) Electronic configuration of He is `1 s^(2) implies `

Which one contradicts the Hund's rule ?

Text Solution

Verified by Experts

'b' is wrong. Correct electronic configuration is `1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 4s^(2)`.
