A chemical compound is the result of chemical reaction of two or more chemical elements which can be further separated from chemical substances to simpler substances. Every chemical compound has its own chemical structure which is made of fixed number of atoms. The atoms are, in turn, joined by way of chemical bonds. However, the molecules of chemical compounds can also be attached together by covalent bonds. |
Salts are attached together by ionic bonds. Metallic compounds attached together by metallic bonds and complex compounds attached together by coordinate covalent bonds. However, pure chemical elements and elemental molecules are made up of several atoms of a single element which includes H2, S8, and others and hence these are not considered as chemical compounds.
Reaction took place between or among elements in order to gain stability. They are said to be in most stable state when there outermost shell of energy have maximum number of electrons which varies from two to eight valence electrons. Noble gases do not react commonly and the main reason behind this is that they already have eight valence electrons in its outermost shell. Helium is the exception in this case which needs two valence electrons to become stable.
The main characteristic that creates differences between the element and compound is their physical and chemical properties. The physical and chemical properties of elements differ completely from their compounds. These properties also help in differentiating a compound from their mixture of elements. However, mixture of elements can be separated by using many methods such as filtration, evaporation or magnetic force, but compounds can be separated only by chemical reaction.
