Question

what is Dalton's atomic theory​

Answer 1

Answer:

According to Dalton's atomic theory, all matter,whether an element, a compound or a mixture is composed of small particles called atoms.

Explanation:

The postulates of this theory may be stated as follows:

• All matter is made of very tiny particles called atoms,which participate in chemical reaction.

• Atoms are invisible particles,which cannot be created or destroyed in a chemical reaction.

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

• Atoms of different elements have different masses and chemical reactions.

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

• The relative number and kinds of atoms are constant in a given compound.

Answer 2

Answer:

Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties.
