Which element 's ionic radius smaller than its atomic radius?
Which element 's ionic radius smaller than its atomic radius?

Solution
The correct option is C sodium
Elements that lose electrons form positive ions that are smaller than atoms of the same element. Therefore the ionic radius of these ions is smaller than its atomic radius. Neon is stable and will neither lose nor gain electrons. N and S will tend to gain electrons, each having a larger ionic radius than atomic radius.
