Why are there only 92 naturally occurring elements?

There are only 88 naturally-occurring chemical elements. … The elements 43, 61, 85 and 87 have no stable isotopes, and none of long half-life, so they are not naturally present. Small amounts are made in nuclear reactions induced by cosmic rays and nuclear tests, but these soon disappear.
