Covalent Bond Basics
Covalent bonds are the result of the sharing of electrons between two or more atoms. These types of bonds form when atoms lack the necessary electrons to achieve a stable electron configuration, and they share electrons to complete their outermost electron shells.
Covalent bonds are commonly found in non-metal elements and are responsible for the formation of molecules.
Covalent bonds form when the atomic orbitals of two or more atoms overlap. These orbitals contain the electrons that are shared between the atoms. The strength of the covalent bond depends on the number of electrons that are shared and the distance between the atoms.
The more electrons that are shared, the stronger the bond. The closer the atoms are to each other, the stronger the bond.
Examples of Molecules Formed by Covalent Bonds
There are many different types of molecules that are formed by covalent bonds. Some common examples include:
- Water (H2O): Water is a molecule that is composed of two hydrogen atoms and one oxygen atom. The hydrogen atoms share their electrons with the oxygen atom to form two covalent bonds.
- Carbon dioxide (CO2): Carbon dioxide is a molecule that is composed of one carbon atom and two oxygen atoms. The carbon atom shares its electrons with the oxygen atoms to form two covalent bonds.
- Methane (CH4): Methane is a molecule that is composed of one carbon atom and four hydrogen atoms. The carbon atom shares its electrons with the hydrogen atoms to form four covalent bonds.

Covalent Bond Properties
Covalent bonds are characterized by a number of properties that influence the behavior of molecules. These properties include bond length, bond strength, and polarity.
Bond Length
The bond length is the distance between the nuclei of the two atoms involved in the bond. It is typically measured in picometers (pm). The bond length is determined by the size of the atoms involved and the strength of the bond.
Stronger bonds tend to be shorter than weaker bonds.
Bond Strength
The bond strength is the energy required to break the bond. It is typically measured in kilojoules per mole (kJ/mol). The bond strength is determined by the number of electrons involved in the bond and the electronegativity of the atoms involved.
Bonds involving more electrons tend to be stronger than bonds involving fewer electrons. Bonds between atoms with similar electronegativities tend to be stronger than bonds between atoms with different electronegativities.
Polarity
The polarity of a bond is a measure of the uneven distribution of electrons between the two atoms involved in the bond. A bond is polar if the electrons are not shared equally between the two atoms. The polarity of a bond is determined by the electronegativity of the atoms involved.
The more electronegative atom will have a greater share of the electrons in the bond.
The properties of covalent bonds have a significant impact on the behavior of molecules. For example, the bond length and bond strength determine the shape of a molecule. The polarity of a bond can affect the solubility of a molecule in water.
Covalent bond properties also influence chemical reactions. For example, the bond strength of a reactant determines the activation energy of a reaction. The polarity of a bond can affect the rate of a reaction.
