There are about 112 elements identified and for the time being 6 more proposed. Out of the first 92 elements, 1 being hydrogen (H) and 92 being uranium (U), there are 90 that are naturally occurring. Technetium (Tc) and promethium (Pm) are man-made elements and do not have any isotopes occurring naturally. All elements after atomic number 92, are man made.
