An element is a single type of atom as defined by its periodic number, which is the number of protons in its nucleus.[1] Hydrogen has only one proton whereas uranium has 92. Uranium is the largest of the stable elements occurring in nature. All known elements are listed on the periodic table, with the heavier ones produced in a laboratory. Chemical compounds are made from joining atoms of the same or different elements. These elements and their compounds make up all matter on the earth and quite possibly all matter outside of the earth as well.
