Element belonging to the same group have the same valency.​

Answer 1

Explanation:

Question :-

Element belonging to the same group have the same valency.

Answer :-

1. The electronic configuration of the outermost shell is same for all the elements belonging to the same group.

2. So, the number of valence electrons for all the elements in a group is the same.

3. The valency of an element is determined by the valence electrons. Hence, elements belonging to the same group have the same valency.

Answer 2

Answer:

Elements belonging to the same group have the same valency because the number of valence electrons in a group is same due to which the tendency of an atom to lose or gain electrons in order to attain nearest noble gas configuration is also same.
