What is an ionic solid? What kinds of forces hold ionic solids together?
Ionic solids are composed of ions. It consists of positively and negatively charged ions and tightly bind together by electrostatic force.
The electrostatic interaction between the charged ion is directly is proportional to the product of the charges on the particles and inversely proportional to the distance between them.
The electrostatic force between two charged ion is F =
Therefore, Ionic solids are held together by the coulombic interactions(electrostatic interaction) between the cations and anions.
