Explanation:
When an atom loses one or more electrons, the resulting ion becomes smaller. If electrons are added to the atom, the ion becomes larger. The ionic radius for an atom is measured in a crystal lattice , requiring a solid form for the compound.

Answer:
Negative ions are bigger than the atoms they come from
Explanation:
The condition stated in question statement can be explained for the cases of negative ions which have radius larger than the actual atomic radi.
This is because a negative ion gains electrons and when electrons are added to the atom, the ion becomes larger and hence the ionic radius increases. The more the electron it gains, the larger will the radius
