two points of Dalton's Atomic Theory
What is elements are composed of very small particles, all atoms of the same element are identical, atoms of one element cannot be changed into atoms of different elements, compounds are formed when atoms of more than one element combine, compounds always have the same relative number and kinds of atoms and atoms can't be created nor destroyed.
