How many types of chemical bond

What is a Molecule?

The elements generally do not exist in the form of atomic (except noble gases) but prefer to form group of atom called Molecules.

What is Bond? :-

The force by which the atomic attract each other to form such group is called a bond.

What is a Chemical bond?

A chemical bond is a force of attraction between atoms that allows the formation of chemical substances that contain two or more atom. The bond is caused by the electrostatic force by attraction between posstive charges or between electrons and nuclei or someetimes as a result of a dipole attration. An electron positioned between two nuclei will be attraction to both of them, and the nuclei will be attracted toward electrons in this position. This attraction constitutes the chemical bond.

Type of Bond-

As started a chenical bond is an attraction between atoms. This attraction may be seen as the result of different behaviour of the outermost electrons of atom . Although all of these behaviors merge into each other seamlessly in various bonding situations so that there is no clear lineto be drawn between them, customartily the chemical bonds are classifeid into differents types.

Atommay attain a stable electronic configuration in three different ways by lossing electron , by gaining or by shairing electron. Moreover, elements may be divided into following three type as: 

1.Electropositive elements: Whose atom give up one or more electron fairly readily:

2. Electronenegative elements: Which will accept electron.

3.Electron which have little tendency to lose or gain electrons.

The different type of bond may br formed depending on the electropositive or electronegative character of atom involved.

Electropositive element+ Electropositive element→ Metallic bond

Electropositive element+ Electronegative element→ Ionoc bond

Electonegative element+ Electronegative element→ Covalent bond
