An element is a pure substance that cannot be decomposed by chemical means to form simpler substances. Elements are the fundamental building blocks of matter. They cannot be changed or broken down into any other simpler substances by chemical reactions. An element is composed only of a single type of atom. Carbon, for instance, contains carbon atom...
A compound is a substance formed when two or more elements combine chemically. When two or more elements participate in a chemical reaction, their atoms exchange electrons, forming chemical bonds. These bonds hold the atoms of the elements together, forming a compound. The type of compound and chemical bond formed depends on whether the elements in...
A mixture is a substance formed when two or more elements or compounds are physically combined. There are no chemical changes in the formation of a mixture. Unlike in a compound, the constituents of a mixture retain their original properties. They can also be easily separated by physical means. Take, for instance, sulfur and iron. When physically c...
