Dalton atomic theory

According to Dolton atomic theory all matter whether an element a compound or a mixture is composed of small particles called atoms .The postulate of this theory may be stayed as follow:

• All matter is made of very thin particles called atoms which participated in chemical reaction.

• Atoms are indivisible particle which cannot be created or destroyed in the chemical reaction.

• Atoms of a given element are identical in mass and chemical properties.

• Atoms of different elements have different mass and chemical properties.

• Atoms combine in the ratio of small whole numbers to form compound.
