GCSE (9:1)
Ion
An atom or group of atoms that has lost or gained electrons and therefore a positive or negative charge.
Polyatomic ion
An ion that is made of more then one atom
Metal ion
an atom which has lost electrons forming a positive ion
Non-metal ion
an atom which has gained electrons forming negative ions.
, Covalent bond
a shared pair of electrons
Molecule
two or more atoms held together by covalent bonds
Metallic bonding
Positively charged metal ions are surrounded by delocalised outer electrons
