An element 'A' belongs to the third period and group 16 of the Periodic Table. Find out the valency of A.
Valency 6
Valency 2
Valency 1
Valency 3

Academic Chemistry NCERT Class 10

Correct Answer: (b) Valency 2

Explanation: As element A belongs to group 16, the electronic configuration will be:

2, 8, 6 The valency of element is 2 as it needs only 2 more electrons to attain a stable gas configuration.
