$\textbf{ \it { \large{ \underline{SIGNIFICANCE OF VALENCE ELECTRONS}}}}$

Those electrons present in the outermost shell of an atom and take part in chemical reaction are known as Valence Electrons.

• The significance is that, they are responsible for determining the chemical behaviour of an atom.

$\textbf{ \it { \large{ \underline{VALENCY : -}}}}$

when atoms of one element combines with the atom of another element to form a compound, they do so in fixed number depending upon the capacity use of the sum to form bonds, it is known as Valency.
