As of 2014, there are 118 elements on the periodic chart.91 of these are generally in the list of naturally occurring elements, with atomic numbers 1 to 92. Technetium, element number 43, is radioactive with a very short half-life, so scientists initially did not believe it occurred naturally; such


Water is a molecular compound formed from the elements oxygen and hydrogen. It is the most abundant molecule on Earth and is essential to life on the planet.


Many different elements are named after people. Some are named after the scientist who discovered the element, while others are named in honor of a famous or noteworthy person.


Elements are named when a suggested name is approved by the International Union of Pure and Applied Chemistry (IUPAC). Most countries use the element name adopted by IUPAC. Names can come from many areas, including science, mythology, geography and chemical properties.
