A radical is defined as an atom or group of atoms with at least one unpaired electron.
Now to start off, all acid radicals are anions but not vice-versa.The same holds between cations and basic radicals too.
Now anions(CL-, SO4-- etc.) are generally termed acid radicals because they are generated from the hydrolysis of acids(HCl,H2SO4 etc).
And cations(Na+, Ba++ etc) are generally termed basic radicals because they are generated from the hydrolysis of bases(NaOH,Ba(OH)2 etc).
