Question

define chemical bond​

Answer 1

Answer:

A chemical bond is a lasting attraction between atoms , ions or molecules that enables the formation of chemical compounds .

Answer 2

Answer :

★ A chemical bond is the attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species.

Two factors due to which atoms interact with each other are

• Decrease in energy due to met attractive forces which are greater than repulsive forces.
• The tendency to achieve noble gas configuration.

There are three types of bonds or linkage which hold the atoms together in a molecule.

• Covalent bond : The bond formed by mutual sharing of electrons between two atoms so as to attain noble gas configuration is called covalent bond.
• Electronegative bond : The bond formed as a result of the electrostatic attraction between the positive and negative ions is called electronegative bond.
• Coordinate bond : It is a special type of covalent bond in which shared pair of electrons come from one atom only$.$
