According to the definition of ionic bond:
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
If we consider the above figure showing formation of ionic bond, due to the transfer of electron from sodium atom to fluorine.It demonstrates clearly, how electrostatic interaction takes place.
In general, electrostatic interaction takes place between two stationary charges.Moreover, electrons would not be static as demonstrated by the above figure.Electrons will be moving at high speed, producing magnetic field around them, due to their motion; and even will also have electric field around them.Thus, we can expect electromagnetic interaction between oppositely charged ions along with electrostatic interaction due to stationary protons.So, does it mean that ionic bond is due to electromagnetic interaction and not just by electrostatic interaction?
[All the statements made are up to my view on the concept.Any correction advisory is welcome]
