All matter consists of indivisible particles called atoms.
Atoms of the same element have same mass and physical properties, but differ from the atoms of other elements.
Atoms cannot be created or destroyed.
Atoms combine with each other in a fixed whole number ratio to form compound atoms.
Atoms of same element can combine in more than one ratio to form two or more compounds.
The atom is the smallest unit of matter that can take part in a chemical reaction.
