Full Answer

Elements are the basic building blocks of matter and are each made up of a single type of atom. Atoms cannot be broken down into smaller particles. Examples of elements include calcium, aluminum, potassium, oxygen and hydrogen. On the other hand, a compound is made up of two or more elements whose atoms have chemically bonded in specific proportions. Compounds have distinct properties that differ from those of their individual elements. Water (H2O) is a compound formed by combining hydrogen and oxygen. Common sugar is a combination of carbon, hydrogen and oxygen.

    What is pure water?

    A:

    The purest water that is theoretically possible would consist of nothing but H2O molecules and exclude substances like minerals and salts. This maximum is never truly achieved for large samples in practice, so the term "pure water" has taken on different meanings that vary by the water's intended use.
