Matter is anything that occupies space and has mass.

image of atom

An atom is the smallest particle of an element which still retains the properties of that element.

An element is a substance which cannot be split up into simpler substances by chemical means.

A molecule is a group of two or more atoms joined together chemically.
A molecule is the smallest part of an element or compound that can exist independently.

A compound is formed when two or more elements combine together chemically.

 

Chemical Bonds are formed when two or more elements combine together chemically - view a demo of bonding
