May 24, 2019 · Covalent bonds, on the other hand, appear to involve two atoms sharing electrons reach a more stable electron configuration. Some compounds contain both ionic and covalent bonds. These compounds contain polyatomic ions. Many of these compounds contain a metal, a nonmetal, and also hydrogen. A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

The chemical equation for this reaction is: KCl + Na ⇌ NaCl + K; It can be noted that when the solid form of potassium chloride is subjected to a flame test, it burns with a pale violet or a lilac-coloured flame, as is the case with most other potassium-containing compounds. Uses of Potassium Chloride A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
