Question

State three significant postulates of Dalton’s Atomic Theory of Matter.

Answer 1

1) Every matter is made up of small particles called atoms.
2) Atoms of a given element are identical in mass as well as in chemical properties.
3) The relative numbers as well as kinds of atoms are constant in a given compound

Answer 2

The main points of Dalton's atomic theory were:Elements are made of extremely small particles called atoms.
Atoms of a given element are identical in size, mass, and other properties;
Atoms of different elements differ in size, mass, and other properties.
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.
