Question

State the valency of the element having:
(i)
6 electrons in the valence shell.
(ii) the electronic configuration of : 2,3​

Answer 1

Answer:

1...1

2. 3

Explanation:

is the valancy of element

Answer 2

Answer:

1. VALENCY = 2

According to octet rules it requires 8 electrons in all to become stable so it already has 6 so it will gain 2

2. Valency= 3

Here dulet rule can be used to use less energy it adopts the path to lost 3 electrons and become stable.
