In one molecule of water, there are two hydrogen atoms and one oxygen atom. Particle diagrams can also show the ratio of atoms of each element in a compound which in turn can tell us the formula o ...

An atom is so small that a single drop of water contains more than a billion atoms. Although tiny, atoms are mostly empty ...

it will likely zip away from you and attach itself to a nearby atom or molecule. An atom becomes radioactive when its nucleus contains too many or too few neutrons. Try to keep the same number of ...
