What do Covalent Bonds involve?

Covalent bonds involve the sharing of electrons between atoms. This type of bond typically occurs between nonmetal atoms that have similar electronegativities. Instead of transferring electrons completely from one atom to another, as seen in ionic bonds, covalent bonding allows atoms to achieve a more stable electron configuration by sharing electrons. This shared pair of electrons enables each atom to fill its outer shell, leading to stability for both.

The sharing takes place in varying degrees depending on the atoms involved. In some cases, one atom may attract the shared electrons more strongly, creating polar covalent bonds, while in others, the sharing is more equal, resulting in nonpolar covalent bonds. Understanding this concept is essential in various applications within beauty therapy, particularly in skin chemistry, as many of the products and ingredients used are based on molecular interactions that rely on covalent bonds.
