Explanation:

A2+ has 2e- less than A, thus increase in positve charge and increase in effective nuclear charge and so reduction in atomic size.

Answer 2

Explanation:

A2+ has 2e- less than A, thus increase in positve charge and increase in effective nuclear charge and so reduction in

atomic size.
