Atomic Theory: the beginning
... Atoms of the same element are identical. Atoms of one element are different from any other element. Atoms of different elements can physically mix or chemically combine with one another in simple whole number ratios. Chemical reactions occur when atoms are separated, joined, or rearranged as a resul ...
