iPolyatomic ion : Polyatomic ions are those ions who aquire either -4 or 4 charge on gaining or losing electron.

Valency : Number of electrons which an atom or element requires to complete its octet i.e. 8 electrons is called valency.But valency is not represented by using +ve or -ve sign.

Isotopes : Elements having same atomic number but different atomic mass.

Isobars : Elements having same atomic mass but different atomic number.
