However, atoms are made up of three types of subatomic particles: the heavy protons and neutrons that make up the nucleus (the central part of the atom), and the much lighter electrons that circle the nucleus in orbital paths called shells

When he conducted his atomic mass experiments with neon gas, he found that a beam of neon atoms subjected to electric and magnetic forces split into two parabolas instead of one on a photographic plate

Dalton had begun his atomic studies by wondering why the different gases in the atmosphere do not separate, with the heaviest on the bottom and the lightest on the top He decided that atoms are not infinite in variety as had been supposed and that they are limited to one of a kind for each element

Elements are characterized by the mass of their atoms Dalton stated that all atoms of an element are identical in shape, size, and mass When atoms are involved in chemical reactions, they combine in small whole-number ratios to form what are now called molecules
