Chemical Compound Formula – Equation and Problem Solved with Example

Chemistry is the science of composition of matter and a beautiful transformation of the physical and chemical properties of an element. The substances are based on matter in Chemistry and its absolute properties too that indicate its identity.

There are different types of chemical compounds that are defined under multiple categories. This classification is generally based on the organic or inorganic compounds. It would be interesting knowing that chemicals having carbon content are organic in nature and chemical compounds that don’t contain any carbon content are inorganic in nature. In Chemistry, most of the chemical compounds fall under organic category only.

A chemical compound is a substance that is formed by combining two or more atoms together. The type of bonding is shared between atoms could be covalent or ionic bonds. For the covalent bonds, the electrons are shared among atoms and for the ionic bonds, electrons are transferred from one to atom to other. When the electrons are shared in the bond, a compound can also be named as the molecule too.

Wring and understanding chemical formulas are the basic skills in Chemistry that define the number of atoms within a molecule. With the help of formula, you can quickly distinguish one chemical compound from other and it gives you complete information related to the compound too. The best idea is to check of chemical arrangement in the periodic table and it will provide the necessary skills how to write the chemical formulas in Chemistry.
