Anabel Shea · Answer 1

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.
