Question

hydrogen forms diatomic molecule while helium remains monoatomic. Explain on the basis of molecular orbital theory?​

Answer 1

Answer:

Hyyy

Explanation:

Explanation: Hydrogen is 1s^1, which is not a full shell. If two of them share electrons, each has a share in two electrons, which is a full shell. Helium is1s^2, which is a full shell, so He is stable as is without forming diatomic molecules.

Answer 2

Explanation:

Hydrogen is 1s^1 , which is not a full shell. If two electrons, each has a share in two electrons ,which is a full shell. Helium is 1s^2 ,which is a full shell so that is stable as is without forming diatomic molecules.
