H - HydrogenHe - HeliumLi - LithiumBe - BerylliumMost elements on the periodic table are metals and have the -ium suffix. Halogen names usually end with -ine, and noble gas names usually have the -on ending. Elements with names not following these naming conventions tend to be ones known and discovered long ago.
Right now, the periodic table is "complete" in that there are no remaining spots in the 7 periods. However, new elements may be synthesized or discovered. As with other elements, the atomic number will be determined by the number of protons within each atom. The element name and element symbol will need to be reviewed and approved by the Internatio...
Fourteen elements are named after people, but only 13 of these names are accepted by the IUPAC. Einsteinium, for example, is named after Albert Einstein, and nobelium is named after Alfred Nobel, the inventor of dynamite. Element 105 also goes by the name Hahnium (after Otto Hahn), but its accepted name is dubnium.

In the fifth century BC, Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, a term derived from the Greek word for “indivisible.” They thought of atoms as moving particles that differed in shape and size, and which could join together.
