Answer 2

Answer:

Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.

• All matter is made up of tiny, indivisible particles called atoms.

• Atoms can be rearranged, combined, or separated in chemical reactions.

• Atoms of different elements can combine with each other in fixed whole-number ratios in order to form compounds.

• Atoms can neither be created nor destroyed. Furthermore, atoms cannot be divided into smaller particles.

• All atoms of a specific element are identical in mass, size, and other properties. However, atoms of different element exhibit different properties and vary in mass and size.

• Atoms of different elements combine in fixed ratios to form compounds.

• Matter cannot be created or destroyed.
