Question

State formation of nitrogen molecule by giving proper diagram.

Answer 1

• Nitrogen has 7 electrons and thus the electronic configuration:2,5.
• Nitrogen atom needs three more electrons to attain stable electronic configuration.
• The nearest noble gas configuration is; neon (2,8).
• When two nitrogen atoms come closer, each contributes three electrons and so they have three shared pairs of electrons between them.
• Both atoms attain an octet, resulting in the formation of a triple covalent bond ($\mathrm{N}\equiv \mathrm{N}$) between them.
