Question

How does the valence of element vary in going down a group?

Answer 1

Answer:

Valency in the periodic table across a period first increases and then decreases. There is no change going down a group. ... The valency does not change going down a group since the bonding behavior is not affected by the core electrons.

Answer 2

Answer:

Valency of elements doesnt change down the group but in a period the valency first increases and then decreases or it continuously increases

Explanation:

If we go down in grp the valence electron in the same group remains same

for Ex. In group valence electron in 1

Therefore valency remains constant in grp.
