Transuranic elements are those beyond what atomic number?
Transuranic elements are those beyond atomic number 92 (uranium). These elements are typically man-made through nuclear reactions and have unstable nuclei, leading to the emission of radiation. Examples include neptunium, plutonium, and americium.

What are transuranic elements?
The transuranic elements are those with an atomic number greater than 92, the atomic number of uranium. Only neptunium (Atomic number 93) occurs naturally on earth, the rest plutonium americium etc are made artificially. See the wikipedia article http://en.wikipedia.org/wiki/Transuranic_elements
There are 92 naturally occurring?
There are 92 naturally occurring elements on the periodic table. Each element is represented by its own unique chemical symbol, such as "H" for hydrogen or "O" for oxygen. These elements make up all matter in the universe.

How many elements are in the elements table?
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.
