Explanation:
The molecule's bond order is 1. The ground state electron configuration of B is 1s2 2s2 2p1. This means that the B2 molecule has 10 electrons organised in MOs.
(σ1s)2 (σ1s)2 (σ2s)2 (σ2s)2 `(π_(2"p"_"y"^1) = π_(2"p"_"y"^1))`
Bond order = `1/2` (Number of bonding electrons − number of anti-bonding electrons)
= `1/2` (6 − 4)
= 1
