Answer:

D

Explanation:

In a binary ionic compound, the charges of both ions must be nuetral in the compound. To balance the charges you would write subscripts accordingly

By definition of ionic bond, the correct answer is option D. The total positive charge must equal the total negative charge.​

Ionic bond

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

In this way, the octet rule is fulfilled, which establishes that the atoms of the elements bind each other in the attempt to complete their valence layer, leaving the atom stable with 8 electrons in its last layer.

Any ionic compound will have a net charge of zero. That is, cations and anions must always combine in such a way that their charges cancel out.

This case

So, in this case, the correct answer is option D. The total positive charge must equal the total negative charge.​
