True or False: In nature, few elements can be found in their elemental form, since most are combined with other elements to form compounds.
Homework Answers
This is true statement.
Reactive elements are present in the form of compound.
But non reactive elements such as gold and copper can be present is elemental form.
So, we have some elements present in elemental form in nature as well.

"Native," or elemental copper can be found in nature, but most copper is mined as oxide or sulfide minerals. Chalcopyrite (CuFeS2) is one copper mineral that can be converted to elemental copper in a series of chemical steps. Reacting chalcopyrite with oxygen at high temperature produces a mixture of copper sulfide and iron oxide. The iron oxide is separated from CuS by reaction with sand (SiO2). CuS is converted to Cu2S in the process and the Cu2S is burned in...
