You might go with 117 elements at the moment, but only 112 have actually been named, the latest being copernicium, although it's not quite official. The elements between 113 and 118, with the exception of 117, have had anywhere between 3 and 80 atoms observed. Element 117 is the only one for which there are no claims for observing any atoms.
118 (all elements from #1 to #118).
