Valency: The number of electrons lost/gained or shared by an atom in a molecule is called its valency.

Nitrogen is an element.

It's symbol is N
It's atomic number is Z=7

Thus, it is the seventh element in the periodic table.

It's electronic configuration is:

(2,5)

[If you are in higher secondary:
Electronic configuration is:
1s2 2s2 2p3

So, the 2p subshell is hall filled and needs 3 more electrons ]

As you see, in the second shell, which is the L shell, there are 5 electrons. The stable configuration is 8 electrons. So, nitrogen needs 3 more electrons to achieve stable state configuration.

So, valency of Nitrogen is 3.
