Final answer:
Ionic bonds are formed through the transfer of electrons between atoms with opposite charges, as seen in the example of sodium and chlorine creating NaCl.
Explanation:
Ionic Bonding: Ionic bonds are formed by the electrostatic attraction between atoms with opposite charges. In the case of sodium (Na) and chlorine (Cl), chlorine takes an electron from sodium, resulting in the formation of Na+ and Cl- ions. These ions are held together by their opposite charges, forming an ionic bond and creating a crystal lattice structure like table salt (NaCl).
