According to Wikipedia:
As of 2013, the periodic table has 114 confirmed elements, comprising elements 1 (hydrogen) to 112 (copernicium), 114 (flerovium) and 116 (livermorium). Elements 113, 115, 117 and 118 have reportedly been synthesised in laboratories however none of these claims have been officially confirmed by the International Union of Pure and Applied Chemistry (IUPAC). As such these elements are currently known only by their systematic element names, based on their atomic numbers.
