Question

check the box that best completes the following statement. in an ionic bond, the ions are held together because... the positive nucleus of each ion attracts the other ions negatively charged electrons. the ions have opposite charges. as the electron moved from one atom to another it pulled the atom along with it. electrons are being shared

Explanation:

Ionic bonds form when electrons are transferred from one atom to another, creating ions with opposite charges. These oppositely - charged ions are then attracted to each other due to electrostatic forces. Sharing electrons is characteristic of covalent bonds. When electrons are moved from one atom to another, the atom losing electrons becomes a positive ion (cation) and the atom gaining electrons becomes a negative ion (anion). The positive nucleus of an ion does not directly attract another ion's electrons in the context of ionic bond formation - it is the overall charge of the ion that matters. The key for ionic bond is the attraction between ions with opposite charges.

Answer:

the ions have opposite charges
