Question

calculate number of electrons present in B2 molecule​

Answer 1

Answer:

Boron has the electronic configuration 1s2 2s2 2p1. So the B2 molecule has two sets of these — six atomic orbitals total. The rule is that n atomic orbitals makes n molecular orbitals, so there are 6 MOs.

Answer 2

Electron present in B2 = 10 e

5 e in single Boron
