The US-based International Union of Pure and Applied Chemistry (IUPAC), the global organization that governs chemical nomenclature, terminology and measurement, verified the elements on 30 December, 2015 after poring over studies dating back to 2004. The scientists who found them must now come up with formal names to replace the clunky Latin- based placeholders – ununtrium, ununpentium, ununseptium and ununoctium – which reflect their atomic numbers, 113, 115, 117, and 118. The atomic number is the number of protons found in an element’s atomic nucleus.
