When oil and water are combined, they do not mix evenly, but instead form two separate layers. An element is characterized by atoms of exactly the same properties, that is, an element is made up of exactly the same atoms. Mixtures can always be separated again into component pure substances, because bonding among the atoms of the constituent substances does not occur in a mixture. Very few samples of matter consist of pure substances; instead, most are mixtures, which are combinations of two . 2 atoms of potassium, 4 atoms of sulfur, and 4 atoms of oxygen.
