Elements and Compounds. Looking at the left side of the chart, we can see that a pure substance can be either an element or a compound. For example, we mentioned that oxygen is a compound as it consists of two oxygen atoms connected by covalent bonds.
A compound is a pure substance which contains identical molecules with two or more types of atomic core. A mixture is a material which has two or more types of molecules. Clearly, these definitions only apply to molecular materials, and will need to be extended to ionic and metallic materials later.
A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together. Note that the two nitrogen atoms which comprise a nitrogen molecule move as a unit. Compounds. Microscopic view of the molecules of the compound water (gas phase).
