Detailed explanation-1: -A covalent bond is formed by equal sharing of electrons from both the participating atoms. The pair of electrons participating in this type of bonding is called shared pair or bonding pair.

Detailed explanation-2: -Covalent Bonds A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms.

Detailed explanation-3: -An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation-a positively charged ion.

Detailed explanation-4: -A covalent bond forms when two non-metal atoms share a pair of electrons . The electrons involved are in the outer shells of the atoms. An atom that shares one or more of its electrons will complete its outer shell. Covalent bonds are strong – a lot of energy is needed to break them.

Detailed explanation-5: -A covalent bond is the force of attraction that holds together two atoms that share a pair of valence electrons. The shared electrons are attracted to the nuclei of both atoms. This forms a molecule consisting of two or more atoms. Covalent bonds form only between atoms of nonmetals.
