English Chemist, 1800s

ATomic StruCTURE: THeory

The theory of atomic structure was introduced and proposed by John ​Dalton (an english chemist) in the 1800's. Dalton's atomic theory is ​about atoms, wherein all matter is made up of atoms, and small, and ​indivisible (which means that atoms cannot be separated) particles. ​Atoms that have different elements are identical and have the same ​mass, while on the other hand atoms with different elements vary in ​size, mass, and chemical behavior. Lastly, atoms cannot be ​subdivided, created, or destroyed.
