Solution
The electronic configuration of Be2 molecule according MOT is (σ 1s)2 (σ* 1s)2, σ 2s2, σ* 2s2.
Explanation:
E.C. of Be atom, 4Be = 1s2 2s2
∴ In Be2 molecule there are total 8 electrons present, which occupy σ 1s, σ* 1s, σ 2s, σ* 2s orbital.
∴ E.C. of Be2 molecule = (σ 1s)2 (σ* 1s)2, (σ 2s)2, (σ* 2s)2
