Chemical elements listed by the discovery year. For chemistry students and teachers: The tabular chart on the right is arranged by the discovery year. The oldest chemical element is Phosphorus and the newest element is Hassium. Please note that the elements do not show their natural relation towards each other as in the Periodic system.
Hydrogen, the lightest element, has one proton in its nucleus, and uranium, the heaviest naturally occurring element, has 92. Element 118 would fit comfortably just below radon in a column of the periodic table containing what are called noble gases for their inert chemical properties.n element s weight is determined by the total number of protons, which have a positive electrical charge, and neutrons, which are neutral, in its nucleus. By that measure, too, the new element is the heaviest ever created.
