One significant difference between an ionic bond, where electrons are taken from one atom and added to another atom, and a covalent or metallic bond, where electrons are shared is

Explanation:

A covalent bond is defined as the bond which is formed due to sharing of electrons between same or different non-metals.

For example, molecule has a covalent bond.

Similarly, when sharing of electrons take place between the same metal atoms then there will be formation of a metallic bond.

For example, metallic bonding occurs between zinc, silver, copper etc.

Thus, we can conclude that one significant difference between an ionic bond, where electrons are taken from one atom and added to another atom, and a covalent or metallic bond, where electrons are shared is the type of bonding.
