- Elements consist of indivisible particles. Dalton named these particles atoms. Atoms make up all matter. Atoms comes from the Greek word ‘atomos’, meaning ‘indivisible’. Dalton did not know what an atom was exactly but knew there must be something to make up so many different elements. These were Dalton’s fundamental building blocks of matter.

Based on all his observations, Dalton proposed his model of an atom. It is often referred to as the billiard ball model. He defined an atom to be a ball-like structure, as the concepts of atomic nucleus and electrons were unknown at the time.
Sep 5, 2019 · What he learned led him to propose several laws, which are known collectively as Dalton's Atomic Theory or Dalton's Laws: Atoms are small, chemically indestructible particles of matter. Elements consist of atoms.
Dalton's Atomic Theory. What are the 5 Points of Dalton's Atomic Theory? Dalton's Atomic Theory was formulated by John Dalton in 1808, and it remains a fundamental tenet of chemistry to this day. The five main points are: Matter is made up of atoms, small and indivisible particles. All atoms of the same element are identical and have the same mass.
