Chemical Compounds

chemical compound is formed by combination of two or more elements into one substance form. In a chemical compound atoms of it's constituent elements are bonded together in molecules. Millions of chemical compounds can be made by combining the roughly 120 chemical elements presently known. 30 million chemical compounds have been already found and identified.

The ratio determining the composition of chemical compound remains fixed. The ratio of each element in a chemical compound is generally expressed by chemical formula like, water which is represented by chemical formula H2O is a chemical compound consisting of two hydrogen and one oxygen atom.

Chemical compounds are further divided into subcategories. Those chemical compounds which are based on carbon and hydrogen atoms are called organic compounds and other chemical compounds which are based on elements other than carbon and hydrogen are called inorganic compounds. Another form of chemical compound which contain bond between carbon and metal are called organometallic compound.



Chemical compounds in which components share electrons are known as covalent compounds whereas compounds consisting of oppositely charged ions are known as ionic compounds.

Talking about property of chemical compounds, a chemical compound may have several possible phases. At low enough temperatures All compounds can exist as solids. Some chemical compounds may also exist as liquids, gases, and even plasmas. Every known chemical compound decompose when heat is applied.
