Do you want to know the difference between Ionic and Covalent bond? We will help you to know the difference and definition by our article.

The ionic bond is the bond in which an electron leaves one atom to join another while the covalent bond is the bond in which there is a sharing of an electron with two atoms. Covalent bonds have a definite shape while ionic bonds do not have a definite shape. The melting point of covalent bond is low and ionic bond is high.

For better understanding, you should understand the terms deeply.

Ionic Bonds

An ionic bond occurs between the metal and non-metal. It involves transfer and accepting of electrons from the valence shells. Ionic bonds are also known as electrovalent bonds. Ionic bond has a high melting point and does not have a definite shape. It is a chemical bond formed by electrostatic attraction between oppositely charged ions.

Ionic bonds are non-directional ionic reactions are comparatively instantaneous. These bonds have a high boiling point. Ionic bonds are solid at room temperature. It has low conductivity. Examples of ionic bonds are NaCl, BeO, LiF, etc.

Covalent Bonds

Covalent bonds are formed by sharing of an electron pair between two atoms. Bond length is highly variable. Covalent bonds are directional and have a definite shape. Covalent bonds are a poor conductor. Covalent bonds are usually solid, liquid or gases. Chemical reactions by covalent bond will be molecular. The polarity of a covalent bond is very low.

Molecular reactions are comparatively slow. Covalent bonds have low melting and boiling point. Compounds are usually soft and waxy. It has very low conductivity. Examples of covalent bonds are Methane, Hydro Chloric acid.

Have a look at the difference between ionic and covalent bond.

Polarity

An ionic bond is highly polar while covalent bonds have low polarity.

Shape

Ionic bonds do not have a definite shape while covalent bonds have a definite shape.

Melting and boiling point

Ionic bonds have high melting and boiling point whereas covalent bonds have low melting and boiling point.

State at Room Temperature

Ionic bonds are solid in room temperature and covalent bonds can be solid liquid and gases.

Bond

Ionic bonds are non-directional while covalent bonds are the directional bond.
