Final answer:
Ionic bonding refers to the transfer of electrons from one atom to another, forming oppositely charged ions that are held together by electrostatic attraction.
Step-by-step explanation:
The type of bonding that refers to a transfer of electron(s) is ionic bonding. In ionic bonds, an electron is completely transferred from one atom to another. This transfer results in the formation of positively and negatively charged ions, which is distinct from covalent bonds where electrons are shared between atoms.
These ions are then attracted to each other due to electrostatic forces. For example, in the formation of sodium chloride (NaCl), an electron from sodium (Na) is transferred to chlorine (Cl), resulting in Na+ and Cl- ions.
