Want to learn more about one of science's heroes from history, Henry Moseley? Moseley solved one of chemistry's greatest puzzles - determining what distinguishes elements from one another and developed a means of identifying elements based on their atomic characteristics. Sadly he lost his life fighting at Gallipoli in WWI.

Only the first 92 of the elements (up to Uranium) occur naturally on Earth. The transuranic elements are produced artificially, and the four most recent additions to the periodic table ares Nihonium (113), Moscovium (115), Tennessine (117) and Oganesson (118). The beauty of the periodic table is its ability to make predictions about the properties of new elements, but the properties of superheavy elements may differ because of relativistic effects.
Above hassium (108), only copernicium (112), nihonium and flerovium (114) have known chemical properties, and copernicium is the only one that has been conclusively categorised. The rest remain elements with unknown chemical properties, for now.
