Types Of Chemical Bonds | Google Science

The presence of a strong force of bond between atoms is referred to as a chemical bond.This bond results stable and has its own properties. The two identical atomic molecules, such as Cl2 , O2, F2 are called homo-atomic molecules. If there are two different atoms in the molecules, such as NO, HCL, term as a hetero-atomic molecule.let’s discuss types of chemical bonds.

Types Of Chemical Bonds

Different Types Of Chemical Bonds

Chemical bonds are mainly classified into three types

1. Ionic or Electrovalent Bond.

2. Covalent Bonds.

3. Metallic Bonds.

Must Read:

According to electronic theory, a chemical bond is said to be formed, when an atom loses, receiving or share electrons, and in doing so, the atom is a stable great gas electronic configuration. One must know the condition for the formation of various types of chemical bonds to understand the concept well.

Conditions for the formation of Ionic Bond

A.It exists between metal and nonmetal.

B.Donar atom has low ionization energy.

C.Electron acceptor atom must have high electron affinity.

Low ionization energy mainly exists in high alkaline and alkaline earth metals and high electron affinity shown by halogen and chalcogens.

Types Of Chemical Bonds

Condition for the formation of Covalent Bond

A.This bond always exists between non-metals.

B.Two atoms mutually Share one, two, three electrons to complete octet.

C.There exists high electronegativity of the element.

D.The ionization energy of elements must be high.

Condition for the formation of Metallic bond

A.Metallic bond exists between the metals only.

B.It is formed when variable atoms share variable electrons.

C.Metallic Bond explained with the help of two models: Electron sea model and Band model.

Other Types Of Chemical Bonds

These types of chemical bonds also play an importance to explain various concepts in chemistry. These are:

1.Coordinate Bond.

2.Hydrogen Bond.

The type of bond decides the physical state, melting and boiling point, electric conductivity, solubility and other factors.

Conditions for the formation of Coordinate Bond

The conditions required for the Formation of coordination bond are:
A. The atom in a bond must have a lone pair to share with another atom, known as the donor atom.
B. The second atom must have an incomplete outermost shell, which calls as an electron acceptor.It has the tendency to take a lone pair.

Types Of Chemical Bonds

Conditions for Hydrogen Bond

A.Hydrogen should be combined with the high electronegative element.

B.An electronegative element should be small in size.

C.These above two criteria have completed obeying by F, O, and N in the periodic table. The size is small enough and electronegativity is strong.
