Full Answer

All elements in their pure form are homogenous. Chemical compounds, which consist of two or more elements chemically bonded together that cannot be physically separated, are also homogenous. This is the opposite of a mixture, which is a heterogenous compound in which the individual components of the mixture can be physically separated. Elements must undergo a chemical change to form compounds, but no change is required for elements to form mixtures.

    Does gold tarnish?

    A:

    Real gold does not tarnish. The metal is not susceptible to oxidization, meaning it does not turn brown, black, green or any other color over time. Dark spots or unnatural hues to a piece of gold indicate impurities and are common in jewelry that is of lower quality.
