There are 92 elements that exist in nature*. Every heavier element has decayed before our time.
Of course, there are more elements in the Periodic Table, but they are all synthetic elements-they were made in a laboratory. Theoretically, there is no limit on how heavy an element could become-you can always add a proton to the nucleus. However these synthetic elements exist only for a fraction of a second and only in particle accelerators. There are currently 115 known elements, 112 of which have been confirmed and are named (or in the process of being named).
*If you extend the term "nature" to other planets and stars, than you will occassionally find more elements.

How many element are there?
In total there are 118 elements known or predicted to exist, and they appear on the modern Periodic Table.Only 114 of the elements are named, having been fully authenticated by isolation, or by detection of decay products. The others are given provisional (numerical) names with their atomic number, but no atomic weight. Around 98 elements occur naturally in one or more isotopes, and about 28 have to be synthetically produced (man-made).

How many natural occurring elements are there?
9290, technetium and promethium are radioactive with short halflives, they do not occur naturally.Of the 118 elements that are known, 94 occur naturally. The elements that do not occur on earth naturally, have been produced artificially. Some of the elements that do not occur on earth naturally have been detected in other parts of the universe. See link for more information.Tc and Pm of number 1-92 had not been found naturally until fairly recently, but now they have. Promethium, technetium, neptunium and plutonium are now considered natural chemical elements as trace quantities have been found in nature; consequently, 94 natural chemical elements.We know today there are 118 elements total. So far.94 are considered natural elements as we can add promethium, plutonium and neptunium to natural elements because these elements exist in nature in ultratiny trace quantities.About thirty native elements are known to occur naturally, by themselves, in pure form, uncombined with other elements into minerals. They include metals like copper, gold, lead, and iron; semi-metals like antimony, arsenic, bismuth, and tellurium, and non-metals like diamond, sulfur, and selenium.Some elements decay into other elements very quickly and very little of them remain. However they can be produced in laboratories and during supernova explosions.90, technetium and promethium are radioactive with short halflives, they do not occur naturally.Astatine has an even shorter half life, being furiously radioactive. Make it 89 ?90 elements out of the first 92 elements are naturally occurringThere are 88 naturally-occurring chemical elements90, technetium and promethium are radioactive with short halflives, they do not occur naturally.98

How many are man made elements of the 118 known elements?
The 26 transuranic elements (elements with atomic numbers higher than 92) are man-made. Some lists also count technetium (element 43) as man-made as well. --------------- Now (January 2013) 97 chemical elements are considered as natural and 21 as man made.
