The Chemical Elements

An element is a chemically pure substance composed of atoms of a single type. The lightest element is hydrogen, which makes up almost 80% of the universe. It is followed by helium, which makes up a bit under 20% of the universe. Other common elements are oxygen, nitrogen, silicon, iron, and carbon.

Stars begin their lives as balls of hydrogen. Stars then fuse hydrogen atoms into helium atoms. An isotope of hydrogen (deuterium), helium and some lithium were created by nucleosynthesis (combining loose protons and neutrons to make nuclei) just after the Big Bang. The next heaviest elements (like carbon, nitrogen, and oxygen) are formed inside stars by nuclear fusion. The heavier elements (like mercury, copper, and gold) are created as massive stars explode in a supernova. Every atom around us and in our bodies was made in the Big Bang or in a star! A few man-made elements, like seaborgium, have been created in laboratories.
