Structure of the Atom
... All the bound protons and neutrons in an atom make up a tiny atomic nucleus, and are collectively called nucleons. The radius of a nucleus is approximately equal to , where A is the total number of nucleons. This is much smaller than the radius of the atom, which is on the order of 105 fm. The nucle ...

... In 1869, a Russian chemist named Dmitri I. Mendeleev (1834–1907) discovered that elements exhibit a repeating pattern of properties when organized in order of increasing atomic mass. He called this observation the periodic law. Mendeleyev arranged the elements in different ways to determine if a rel ...
