AGHS- Atomic Theory

All matter is composed of extremely small particles called atoms, which cannot be subdivided, created, or destroyed.

Atoms of a given element are identical in their physical and chemical properties.

Atoms of different elements differ in their physical and chemical properties.

Atoms of different elements combine in simple whole-number ratios to form compounds.

In chemical reactions, atoms are combined, separated, or rearranged but never created, destroyed, or changed.
