They of all time combine in equal amounts and atoms cannot be created, divided, or destroyed. after(prenominal) Dalton came up with the atomic theory JJ Thomson said that atoms were like balls of lord ly charge that contained a number of electro! ns this was in 1897. To describe his theory better he came up with a Plum pudding model this was an atom with electrons surrounded by a positive charge. This was later then disproved by Ernest Rutherford who was Thomsons former student. Rutherford was in addition known as the father of nuclear physics. What he had find was that atoms had a small dense nucleus that contained...If you want to watch a full essay, order it on our website: BestEssayCheap.com
