Which of the following represents a type of ionic bonding?

Ionic bonding occurs when there is a transfer of electrons from one atom to another, resulting in the formation of charged ions. In this process, one atom donates an electron and becomes positively charged, while the other atom receives the electron and becomes negatively charged. The result is that these oppositely charged ions experience a strong electrostatic attraction, which holds them together in a stable compound.

This attraction between oppositely charged ions is fundamental to ionic bonding. It leads to the formation of ionic compounds, such as sodium chloride (table salt), where sodium ions (Na⁺) and chloride ions (Cl⁻) bond together.

The other options describe different types of interactions: sharing of electrons pertains to covalent bonding, the fusion of atomic nuclei relates to nuclear fusion processes, and the simple attraction between neutral atoms can refer to van der Waals forces or other weak interactions. None of these describe the nature of ionic bonding, which is specifically characterized by the formation and attraction of charged ions.
