The periodic table of elements (periodic table) is a table that contains all the known chemical elements. The periodic table today contains 94 chemical elements that are natural and 24 that have only been synthesized in a lab, in a nuclear reactor, or in a nuclear explosion. Each chemical element on the periodic table is assigned an element name, an atomic number and its atomic weight. The atomic number is how many protons are in the nucleus of every atom of that element. The atomic weight is the total number of protons and neutrons in the atom.

The 94 naturally occurring elements on the periodic table belong to one of seven periods and one of four blocks. Periods are horizontal rows on the periodic table, so if a chemical element is on row three it’s in period three. The blocks on the periodic table go from left to right in the following order s-block, f-block, d-block and b-block. The blocks on the periodic table represent the sequence in which the electron shells of the elements are filled.

The 94 naturally occurring elements on the periodic table belong to one of eighteen groups. The eighteen groups on the periodic table are the lithium group, beryllium group, scandium group, titanium group, vanadium group, chromium group, manganese group, iron group, cobalt group, nickel group, copper group, zinc group, boron group, carbon group, nitrogen group, oxygen group, fluorine group and helium group.
