92 elements are found in nature (#92 is uranium) but those with atomic numbers up to 118 have been synthesized so far, except for #117.
The heavier an element gets the more unstable it is, so the higher-numbered ones only last fractions of a second before they decay into lighter elements.

Various references will cite different numbers around 110 elements. As scientists continue to experiment with particle accelerators and cyclotrons, they will be able to make more elements. Many of the manmade elements on the periodic table only last for a few milliseconds before they break apart.

There are about 118 elements.
They are specified on http://en.wikipedia.org/wiki/List_of_elements_by_number
