Dalton's Atomic Theory
Made by: John Dalton
Atomic theory is the idea that all matter is made up of tiny particles called atoms. Atoms are like the building blocks of everything around us. Each element, like gold or oxygen, is made of its own kind of atom. These atoms can join together to form molecules, which make up the substances we see, touch, and use. the theory also says that atoms cannot be created or destroyed in ordinary chemical reactions only rearranged. -
