Answer 1

Valency:

• “Valency is the combining capacity of an atom.”
• “The electrons present in the outermost shell of an atom are known as the valence electrons.”

The valency of N:

• Nitrogen is a chemical element with an atomic number $7$ and an atomic symbol $\mathrm{N}$.
• The electronic configuration of $\mathrm{N}$ is $1s^{2}2s^{2}2p^3$.
• Nitrogen has $5$ electrons in its valence shell.
• Its valency is $3$.
