Use molecular orbital theory to explain why the Be2 molecule does not exist.
The electronic configuration of Beryllium is 1s2 2s2.
From the electronic configuration it is clear that there is no singly filled atomic orbital present in beryllium.
Without the half- filled orbital, the overlapping is not possible, therefore Be2 molecule does not exist.
Following results are observed when sodium metal is irradiated with different wavelengths.
Calculate (a) threshold wavelength and, (b) Planck’s constant.
λ (nm) | 500 | 450 |
400 |
v × 10–5 (cm s–1) | 2.55 | 4.35 | 5.35 |
