Question

25.Which of the following increases along the period?​

Answer 1

Explanation:

A) Atomic size decreases on moving along a period from left to right due to increase in effective nuclear charge.

C) Metallic character(ability to loose electron) decreases on moving along a period from left to right due to decrease in size and increase in effective nuclear charge.

D) Ionic size decreases for metals forming cations on moving along a period from left to right as the metals loose their outer electrons. But it increases for non metals forming anions as effective nuclear charge decreases.
