Question

state the various postulates of Dalton atomic theory of matter.​

Answer 1

Some of his basic postulates were:

• All matter is made up of very small, discrete particles called atoms.
• All atoms of an element are alike in weight, and this weight is different from that of any other kind of atom.
• Atoms cannot be subdivided, created or destroyed.
• Atoms of different elements combine in simple whole-number ratios to form chemical compounds.
• In chemical reactions, atoms are combined, separated, or rearranged.

These are some of the most important points of his postulates. While there are several other points, I believe these points should be sufficient for school studies or SAT preparation.
