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: -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: -In a polar covalent bond, the electrons are unequally shared by the atoms and spend more time close to one atom than the other.
Detailed explanation-4: -The bonded atoms form a molecule. A molecule is a neutral group of atoms joined by covalent bonds. By sharing 2 electrons in a covalent bond, each atom gains a stable set of 8 valence electrons.
