(9) Which is true from the following ?
fredd [130]

Answer:

The correct answer is A and D.

Explanation:

Please I want brainliest.

Reason:

The size of the ions follows the order:

Negatively charged ion > Neutral atom >

Positively charged ion

This is because of the size of ions increases when the electrons are added to the outermost shell of an atom.

This happens due to the increase in

electron-electron repulsion.

Moreover, when the electrons are removed from an atom, then the affective nuclear charge that is experienced by the outermost electron increases.

Thus the size of the positively charged ion is least.
