John Dalton’s atomic theory:
1) All elements consist of minuscule particles called atoms.
2) All atoms of a given element have are identical to each other.
3) All atoms of a given element are different than those of other elements.
4) Atoms of one element combine with other elements to create compounds. They always combine in equal amounts.
5) Atoms cannot be created, divided, nor destroyed.
This idea was accepted in the early 1800’s because most of his points in his theory were valid. He basically took old theories about atoms and experimented with them and recorded his results which came to be Dalton’s atomic theory that laid the groundwork for today’s atomic theory. His theory is saying that atoms were tiny and indestructible particles which were a certain size, mass, and chemical behaviordepending on the element they were.
