Question

sarah is asked to sort out the list of ions and ionic compounds. how can sarah differentiate between the ions and ionic compounds?
○ ions have a positive or negative charge, but an ionic compounds overall charge is zero.
○ ions have no charge, but ionic compounds have a positive charge.
○ ions have no charge, but ionic compounds have a negative charge
○ ions have a positive or negative charge, but an ionic compounds overall charge is negative.

Explanation:

Ions are atoms or groups of atoms that have gained or lost electrons, resulting in a positive or negative charge. Ionic compounds are made up of positive and negative ions. In an ionic compound, the total positive charge of the cations equals the total negative charge of the anions, so the overall charge of an ionic compound is zero.

Answer:

Ions have a positive or negative charge, but an ionic compound’s overall charge is zero.
