Ionic bonds occur through the attraction of oppositely charged ions formed by the transfer of electrons. For example, sodium and chlorine combine to form sodium chloride, where sodium loses an electron and becomes positively charged, while chlorine gains an electron and becomes negatively charged. This attraction leads to the formation of ionic compounds. ;
Ionic bonds occur when oppositely charged ions attract, resulting from the transfer of electrons from one atom to another. The process forms cations and anions, which bond together due to their electric charge. Therefore, the correct answer is A.
