Out of the 118 elements in the periodic table, about 94 are naturally occurring. These include the ones that exist in nature through natural processes, like through radioactive decay or in stellar processes. These are elements with atomic numbers 1 through 92, plus a few others that have been found in trace amounts in nature (like plutonium-244).
