Difference between S and `S^(2-)` as `S^(2-)` has

Options

A. Larger radii and larger size
B. Smaller radii and larger size
C. Larger radii and small size
D. Smaller radii and small size

Answer

A

Explanation

Difference between `S and S^(2-)` implies larger radii and larger size of `S^(2-)`.
As the radii of the anion is always larger than the atomic radii of its parent atom. In an anion as electron or electrons are added to the neutral atom the nuclear charge acts on more electrons so that each electron is held less tightly and thereby the electron cloud expands.
