Verified Solution • 2025–26 Session moderate

In the molecular orbital diagram for the molecular ion, N₂⁺, the number of electrons in the

σ

_{2p_z} molecular orbital is :

Accepted Answer

Electrons in

N_{2}^{+}

= 7

\times

2

-

1 = 13

Moleculer orbital configuration of

N_{2}^{+}

(13)

=

σ_{1 s^{2}} σ_{1 s^{2}}^{*} σ_{2 s^{2}} σ_{2 s^{2}}^{*} π_{2 p_{x}^{2}} = π_{2 p_{y}^{2}} σ_{2 p_{z}^{1}}

∴

σ_{2 p_{z}}

no. of electrons = 1.
