GENERAL KNOWLEDGE

Detailed explanation-1: -Sharing of an electron pair between the atoms results in the formation of covalent bonds. During bond formation, each bond consists of two electrons which are contributed by each one of the combining atoms. By the mutual sharing of electrons, each atom attains octet configuration in its valence shell.

Detailed explanation-2: -A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

Detailed explanation-3: -Covalent bonding involves the sharing of electrons between two or more atoms. Ionic bonds form when two or more ions come together and are held together by charge differences.

Detailed explanation-4: -A Double covalent bond is formed when two pairs of electrons are shared between the atoms rather than just one pair.
