Daltons Atomic Theory

You will learn about Daltons Atomic Theory in this video. John Dalton was an English chemist who is very well known today for his work in the development of atomic theory. Let us learn the postulates of Daltons atomic theory. All matter, whether an element, a compound or a mixture are made up of very tiny particles called atoms. All atoms of a given element are identical in size, mass and chemical properties. Atoms of different elements differ in size, mass and chemical properties. Atoms are indivisible particles which can neither be created nor destroyed in a chemical reion. Atoms combine together in fixed whole number ratios to form compounds. In a chemical reion, atoms only get rearranged. An atom of an element does not change into the atom of another element.\r
