How does the radius of a nitrogen ion with a −3 charge compare to that of neutral nitrogen?

The radius of the atom has been increased with the acquisition of the-3 charge.

The radius of an atom has been defined as the distance of the nucleus to the outermost electron. The loss and addition of electrons to the atom has results in the charge along with the change in radius.

The negative charge to the atom has been imposed with the gain of electrons. Thus, the nitrogen ion has been formed with the gain of 3 electrons.

The increase in the number of electrons results in the increased repulsion to the outermost electron from the nucleus. Thus, the radius of the atom has been increased with the acquisition of the-3 charge.

The radius of a nitride ion is much larger than that of a nitrogen atom.

Explanation:

You are adding three extra electrons to the same energy shell.

This greatly increases electron repulsions.

The volume increases to give the electrons more room and decrease the repulsions.

The radius increases by a factor of 2.3 and the volume increases by a factor of 12.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
