In addition, any new element must be assigned a temporary name and symbol, and if validated, given an official name. Such was the case when IUPAC recently reviewed elements 113, 115, 117 and 118, and decided to give them official names and symbols (goodbye, ununseptium and hello, tennessine!).

In chemistry, an element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei.Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by chemical means.

For example, a hydrogen atom has 1 proton, while a carbon atom has 6 protons. Varying the number of electrons in an atom of an element produces ions. Changing the number of neutrons produces isotopes. Interactive periodic table showing names, electrons, and oxidation states. Visualize trends, 3D orbitals, isotopes, and mix compounds. Fully descriptive writeups.

Three subatomic particles compose elements: protons, neutrons, and electrons. Protons, which have an electrical charge of +1, and neutrons, which have a neutral charge, make up the nucleus of an element. This video explains the Elements and Compounds.
