These are the 4 major points of Dalton's Atomic Model
-All elements made of atoms that cant be divided
-All atoms of the same element are the same and different elements are different
-An atom of one element cant change into another one. Atoms cannot be created or destroyed, only rearranged.
-Every compound is made of a specific ratio of specific atoms.
