Consists of
different types of
atoms that are not
chemically bonded
Compound
Particles are held together by
strong forces called chemical
bonds. A chemical reaction will
have taken place
Molecules
Combinations
of atoms
Ionic Bonding
This happens in compounds consisting of
a metal and non-metal. Electrons are
transferred from the metal atom. Oppositely
charged ions are formed which are bonded
together by electrostatic attration. The metal
ion is positive and the non metal ion is
negative
Covalent Bonding
Occurs in compound of 2 non
metals. Electorns are SHARED
between the atoms
Metallic Bonding
This occurs in metals. Electrons
are shared between the atoms
