Ions are atoms with extra electrons or missing electrons. Positive ions or cations are molecules that have lost one or more electrons whereas negative ions or anions are actually oxygen atoms with extra negatively charged electrons.

Complete step by step answer:
-The negative and positive ions are held by electrostatic force of attraction. This results in the formation of ionic bonds or electrovalent bonds.
-The electrostatic force also known as Coulomb’s force or Coulomb’s interaction is the attractive or repulsive force between two electrically charged objects. Like charges repel each other while unlike charges attract each other.
-While protons and electrons are attracted by electrostatic forces, protons don’t leave the nucleus to get together with electrons because they are bound to each other and to neutrons by the strong nuclear forces.
-Examples of electrostatic forces are:
1.Balloons get attracted to another balloon when one of them is rubbed with hair.
2.When we run a piece of paper with oil in our head with the help of a comb produces electrostatic force.
3.Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves.

Hence, option C is correct.

Coulomb’s law is extremely important in chemistry and physics because it describes the force between parts of an atom and between atoms, ions, molecules, and parts of molecules. As the distance between the charged particles or ions increases, the force of attraction or repulsion between them decreases and the formation of an ionic bond becomes less favorable. When charged particles move closer to each other, energy increases and ionic bonding is more favorable.
