Radical
Radical is an atom or a group of atoms of same or different elements which behaves like a single atom with a positive or a negative charge on it.
Radicals have their own combining power based on which they form chemical formulae.
A radical can be either a basic radical having positive charge i.e, cation or a radical having negative charge i.e, an anion.
