How many elements are there in the periodic table?
As of my last update in April 2023, there are 118 confirmed elements in the periodic table. This includes all naturally occurring elements as well as synthetic elements that have been created in laboratories. The most recently added elements were numbered 113 (Nihonium, Nh), 114 (Flerovium, Fl), 115 (Moscovium, Mc), 116 (Livermorium, Lv), 117 (Tennessine, Ts), and 118 (Oganesson, Og), all of which were added between 2011 and 2016. The periodic table is subject to change as new elements are discovered and synthesized.
