Question

What is ion polarization?

Answer 1

1. Ionic polarization occurs in ionic compounds, in which the oppositely charged ions move in opposite directions under the influence of the electric field to produce a net dipole moment in them.
2. The lattice vibrations causes the ions to move, the relative displacement of the ions in the compound causes the center of the charges to be different, which are affected by the symmetry of the displacements.
3. When these centers do not correspond with each other, it leads to the rise of polarization. This polarization is called the ionic polarization.
4. The compounds that show this type of polarization are $\mathrm{NaCl},\mathrm{KCl},\mathrm{etc}.$
