What are the main ideas in dalton's atomic theory?

Main points/ideas in Dalton's Atomic Theory:

1. All matter is composed of extremely small particles called atoms.
2. Atoms of a given element are identical in size, mass, and other properties; Atoms of different elements are different in size,mass, and properties.
3. Atoms cannot be divided, created, or destroyed.
4. Atoms of different elements combine in simple whole number ratios to form chemical compounds.
5. In chemical reactions, atoms are combined, separated, and rearranged.

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.
