Chemical Elements List
(Chemical Elements are Listed with Links to Information about Each Chemical Element)
Chemical Elements are substances that cannot be decomposed or broken into more elementary substances by ordinary chemical means.
Elements were at one time believed to be fundamental substances, but they are now known to consist of a number of different elementary particles.
More than 100 chemical elements are known to exist in the universe, although several of these, the so-called transuranium elements, have not been found in nature, and can only be produced artificially.
