Explain the main postulates of Dalton s atomic ... - SS2 Chemistry Atomic Structure and Periodicity Question

Dalton's atomic theory consists of four main postulates:

A.    All matter is made up of indivisible particles called atoms.

B.    Atoms of the same element are identical in their properties, such as size, mass, and chemical behaviour.

C.   Atoms combine in simple whole-number ratios to form compounds.

D.   Chemical reactions involve the rearrangement of atoms, but no atoms are created, destroyed, or changed into atoms of another element.

Dalton's theory laid the foundation for modern atomic theory by introducing the concept of atoms as fundamental building blocks of matter. It provided a theoretical framework that explained chemical reactions and the behaviour of elements. However, subsequent discoveries, such as the existence of subatomic particles, revealed limitations in Dalton's theory.
