Question

Give an example of a chemical element which forms a diatomic molecule.

Answer 1

Diatomic molecule:-

1. Molecules that have atomicity of 2 are called diatomic molecules
2. Example of a diatomic molecule is Nitrogen.
3. Nitrogen gas with formula ${\mathrm{N}}_2$exists as a diatomic molecule.
4. It can form $\mathrm{p\pi }-\mathrm{p\pi }$multiple bonds.
5. Also both the nitrogens are bonded with a triple bond, which is very strong and cannot be broken easily.
6. This is also a reason why Nitrogen molecule does not react easily.

Therefore, Nitrogen forms a diatomic molecule$\left({\mathrm{N}}_2\right)$.
