Elements:
Elements are the basic chemichals of the universe. Each elementis made from only 1 kind of atom, with a certain number of sub-atomic particles & it's own unique character. Now, more than 115 have so far been identified. Each element is listed in a perioic table. At least 20 of the most recently discovered elements were created by scientists & do not exist naturally. All the most recently discovered contain very large, heavy atoms. Very few elements occur naturally by themselves. Most occur in a combination with others in compounds. Gold is one of the few elements found as a pure 'native' element.
