All together there are 117 elements on the periodic table, 94 of which occur naturally on earth. According to Wikipedia, there are 117 elements that have been isolated or synthesized, with a gap between element 116 and element 118. They do also show a wide (extended) format of periodic table with additional elements that have not been discovered, isolated, or synthesized on earth.
