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. The covalent bonds are also termed as molecular bonds.

Detailed explanation-2: -Covalent bonds involve the sharing of electron pairs between atoms. Electron pairs shared between atoms of equal or very similar electronegativity constitute a nonpolar covalent bond (e.g., H–H or C–H), while electrons shared between atoms of unequal electronegativity constitute a polar covalent bond (e.g., H–O).

Detailed explanation-3: -Covalent bonds form primarily between nonmetal elements, although these types of bonds can occur between metals and nonmetals. A covalent bond is one in which atoms share their valence electrons. Valence electrons are the electrons located in the outer shell of the atom, and they are involved in bonding.
