Final answer:
Ionic bonds are held together by an electrostatic attraction between oppositely charged ions. The strength of the ionic bond is determined by the quantity of the charges and the distance between the charged particles.
Step-by-step explanation:
An ionic bond is the electrostatic attraction that holds ions together in an ionic compound.
Oppositely charged particles attract each other due to the opposite charges of cations and anions.
This attraction is referred to as an electrostatic force of attraction.
The ionic bond is stronger when the charges on the ions are greater and weaker when the ions are larger, resulting in a greater distance between the charges.
