Dalton's atomic theory
|
1. elements are made of tiny particles called atoms
2. all atoms of a given element are identical 3.the atoms of a given element are different from those of any other element 4. atoms of one element can combine with atoms of other elements to form compounds. a given compound always has the same relative numbers and types of atoms 5. Atoms are indivisible in chemical processes. atoms are not created or destroyed in chemical reactions. |
