Answer 2

Step-by-step explanation:

The electrons that are present in the outermost shell / orbit of an atom are called Valence Electrons.

For example ,

Sodium , Na has 2 electrons in its first orbit , 8 electrons in its second orbit and 1 electron in its outermost / third orbit.

Here , only 1 electron is present in the outermost orbit of the Sodium atom . So , this 1 electron is the valence electron.
