Question

Among H₂ ,He₂⁺ ,Li₂ ,Be₂ ,B₂ ,C₂ , N₂ ,O⁻₂, and F₂, the number of diamagnetic species is
(Atomic numbers: H = 1, He = 2, Li = 3, Be = 4, B = 5, C = 6, N = 7, O = 8, F = 9)

Answer 1

Answer:

Six species are diamagentic as all electrons are paired. These are H2 (σ 1s)2 , Li2 KK (σ 2s)2 , Be2 KK (σ 2s)2 (σ * 2s)2 , C2 KK (σ 2s)2 (σ * 2s)2 ...............
