           Elements are everywhere: some you                               Elements in our world
           can see, like gold, others are almost                           There are 118 elements in the periodic table;

           invisible, like oxygen gas. An element                          92 of them are found in nature, while the

           is a substance that cannot be broken up                         is unique. Most of the elements are solids,
           into simpler ingredients. Each one is made                      like the metals. At room temperature,
                                                                           11 elements are gases, while bromine

           which are unique for every element.
           Most elements are joined with other
           elements to make compounds,

           which are made by combining two
           or more elements. This includes
           water, which is a compound
           of hydrogen and oxygen.
