Question

Arrange the following ions by ionic radius: N3-, O2-, F-. Describe your reasoning.

Accepted Answer

N3- \u003e O2- \u003e F-; N3- has more electrons leading to higher repulsion.

Answer

O2- \u003e N3- \u003e F-; Ionic size decreases with more negative charge.

Answer

F- \u003e O2- \u003e N3-; F- is smaller due to positive nuclear charge.

Answer

All have the same ionic radius; they are isoelectronic.
