The atoms which gain electrons to attain their nearest noble gas configuration are called anions.
The atoms which are ready to lose electrons to attain their nearest noble gas configuration are called cations.
In case of anions ,electrons are added so that size increases as the number of electrons are more when compared to number of protons .so protons cannot bind that much electrons . Anions have large size than their parent atom .
In case of cations,electrons are removed so that size decreases as the number of electrons are less when compared to number of protons.so electrons are attracted more towards the nucleus . Cations have small size than parent atom.
Finally we can conclude the sizes as
