Chemical bonds are formed by joining the atoms that have valence-free electrons.
The chemical bonds are formed by the loss, gain, or sharing of electrons.
There are numerous types of bonds that can be possible such as an Ionic bond, Covalent bond, Metallic bond, Hydrogen bond, etc all the bonds have unique specified properties of their own.
The strongest bond in Chemistry is the covalent bond.
These are the bonds that are formed by the sharing of electrons of one atom with another.
The free electrons or valence shell electrons of one atom will combine with the other atom in a similar manner.
Example: Water molecule forms the covalent bond.
The bond formation occurs as follows:
The formation of the water molecule is as follows:
