What is the difference between a covalent bond and an ionic(electrovalent) bond?

A covalent bond is a type of chemical bond that occurs when two atoms share electrons. In this bond, the electrons are not transferred from one atom to another, but rather they are shared between the atoms. This sharing of electrons creates a strong bond between the atoms.

On the other hand, an ionic (electrovalent) bond is a type of chemical bond that occurs when there is a complete transfer of electrons from one atom to another. In this bond, one atom loses electrons to become positively charged (cation), while the other atom gains those electrons to become negatively charged (anion). The resulting attraction between the oppositely charged ions creates the bond.

To summarize, the main difference between a covalent bond and an ionic bond is the way electrons are shared or transferred between atoms. In a covalent bond, electrons are shared, while in an ionic bond, electrons are transferred.
