John Dalton's atomic model's name is the "billiard ball" model. This is because, according to Dalton, there are many different atoms and they cannot be broken into smaller pieces.
According to Dalton, who was born in 1766, atoms cannot be destroyed even during a chemical reaction. All matter is comprised of atoms with a particular element having the same type of atoms. Two or more different kinds of atoms can react with each other chemically to form a compound. This happens in a fixed and expected ratio.
Dalton, who was born to a Quaker family, spent much of life teaching and carrying out research. He was interested in meteorology and keeping records.
