How do an ionic bond and a covalent bond differ?

An ionic bond is an attraction between oppositely charged ions. A covalent bond is a sharing of electrons between atoms.

A covalent bond is an attraction between oppositely charged ions. An ionic bond is a sharing of electrons between atoms.

There is no difference. Both an ionic bond and a covalent bond share electrons.

There is no difference. Both an ionic bond and a covalent bond are attractions between oppositely charged ions.

Ionic bonds and covalent bonds are both types of chemical bonds.
Ionic bonds are types of chemical bonds that are formed between a metal and non-metal atoms.
Ionic bond formation involves the transfer of electrons from a metal atom to a non-metal atom. For example from a potassium atom to a chlorine atom.
Metallic atom loses electrons to form a positively charged ion and non-metallic atom gains electrons to form a negatively charged ion.
The electrostatic attraction between the oppositely charged ions results in an ionic bond.
A covalent bond, on the other hand, occurs between non-metal atoms as a result of sharing electrons. For example, in a chlorine molecule, two chlorine atoms share electrons to form a chlorine molecule.
