Detailed explanation-1: -A Nonpolar Covalent Bond is created when atoms share their electrons equally. This usually occurs when two atoms have similar or the same electron affinity. The closer the values of their electron affinity, the stronger the attraction.

Detailed explanation-2: -Covalent bonds. Another way atoms can become more stable is by sharing electrons (rather than fully gaining or losing them), thus forming covalent bonds. Covalent bonds are more common than ionic bonds in the molecules of living organisms.

Detailed explanation-3: -In a single covalent bond, when the electrons are shared between two s orbitals, the resulting bond is a sigma () bond as shown in Figure 3-4. Sigma bonds are the strongest covalent chemical bonds.

Detailed explanation-4: -In chemistry, a covalent bond is the strongest bond, In such bonding, each of two atoms shares electrons that bind them together. For example-water molecules are bonded together where both hydrogen atoms and oxygen atoms share electrons to form a covalent bond.

Detailed explanation-5: -Covalent bond is formed by sharing of electrons between the atoms.
