The Periodic Table
... Atoms of the same element always have the same number of protons. This identifies them as the element that they are. But all atoms of an element don’t have to have the same number of neutrons. For example, all boron atoms have 5 protons. However, four-fifths of them have 6 neutrons and one-fifth of ...
