Question

2. The valency of helium is zero.

• A. True
• B. False

Answer 1

The correct option is A True

• The combining capacity of an atom is known as its valency.
• Noble gases have fully filled outermost shell and hence stable and zero valency.
• Helium has 2 electrons in its outermost orbit thus stable. It does not lose or gain electrons. Therefore, the valency of helium is zero.

Therefore, the given statement is true.
