Q

State the 6 Dalton’s atomic theory

A
  1. All matter is comprised of tiny, definite particles called atoms.
  2. Atoms are indivisible and indestructible.
  3. All atoms of a particular element share identical properties, including weight.
  4. Atoms of different elements contain different mass. And
  5. Atoms of different elements combine in fixed whole-number ratios when forming compounds.
