Electrovalent Bonds vs. Covalent Bonds: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 19, 2024
Electrovalent bonds involve electron transfer and ionic compound formation, while covalent bonds involve electron sharing and molecule formation.

Key Differences

Electrovalent Bonds form through the complete transfer of electrons from one atom to another, resulting in ions. These ions are held together by electrostatic forces. Covalent Bonds, in contrast, occur when two atoms share electrons, resulting in a molecule. This sharing can be equal or unequal, affecting the molecule's properties.

In Electrovalent Bonds, one atom becomes a positively charged cation and the other a negatively charged anion. This bond typically forms between metals and nonmetals. Covalent Bonds are common between nonmetal atoms, where electrons are shared to fulfill each atom's octet rule, leading to a more stable configuration.

Electrovalent Bonds generally create solid compounds at room temperature, with high melting and boiling points due to strong ionic bonds. Covalent Bonds, however, can result in various states of matter, with generally lower melting and boiling points, as the intermolecular forces are weaker.

The compounds formed by Electrovalent Bonds are usually soluble in water and conduct electricity when dissolved, due to the presence of free ions. Covalent Bonds form molecules that are often insoluble in water and do not conduct electricity, as there are no free ions.
