Question

Which of the following properties generally increases on moving from top to bottom ?

• A. Ionisation energy
• B. Nonmetallic character
• C. Atomic size
• D. Valency

Answer 1

The correct option is C

Atomic size

Atomic size increases as we move from top to bottom due to the addition of new shells.

Ionisation energy and nonmetallic character decreases down the group where as the valency remains constant.
