Every chemical compound is made up of atoms and molecules and the attraction between these atoms and molecules is known as a chemical bond. Chemical bonds are normally created when two different compounds have different electrons and nuclei and when there is an electromagnetic force between the two chemical compounds.
There are mainly three kinds of chemical bonds, which are normally segregated into two different categories. Ionic bonds and Covalent bonds are normally termed as strong bonds and polar covalent bonds are termed as weak bonds.
Covalent bonds are one of the most common chemical bonds where the electronegativity between the atoms of two different chemical compounds is almost non-existing. Hence, the atoms of both the chemical compounds share their electrons, and these chemical compounds are normally organic in nature.
Polar Covalent bonds are somewhere between covalent bonds and ionic bonds and therefore, this kind of chemical bond involves sharing of electrons. These chemical bonds are normally formed when atoms in both the chemical compounds are very different from each other in nature. One of the simplest examples of such chemical bond is water.
Ionic bonds are chemical bonds where two chemical compounds have huge electronegativity differences. Hence, in such chemical bonds’ electrons are transferred completely to complete the reaction. For example, Ionic chemical bonds are present in sodium chloride as one electron is moved to form an ionic bond with chlorine.
