What elements are found as elements?
well some of the nature elements are known as Fire, Water, Earth, and Air Another answer I think what you may mean is what elements (chemical elements - not those in the answer above) are found in an uncombined form in nature. Well, not many. Gold is one. Nitrogen gas, oxygen, all the inert gases are others
