Are there really 98 naturally occurring elements?
The usual textbook answer is 91. Scientists used to believe that, except for the element technetium, all the elements up to element 92 (uranium) could be found in nature. However, it turns out there are other elements that occur in trace amounts naturally. This brings the number of naturally occurring elements to 98.

Can there be infinite elements?
Since an element is determined by the number of protons it has, could you theoretically just keep adding protons and forming new elements infinitely? The answer is no.
Are there more than 118 elements?
Answer 1: So far we have identified ~118 chemical elements (four of them are still not officially recognized). Only the first 98 are known to occur naturally on earth, the rest have been made synthetically. About 32 of them occur on earth as pure elements, and the rest occur in combinations in compounds.
