Explanation:
The given data is as follows.
Electric field between plates without dielectric, 
Electric field between the plates with dielectric,
.
Permittivity of free space,
= 
Now, we will determine the charge density as follows.

= 
= 
Thus, we can conclude that the charge density on each surface of the dielectric is
.
Yes it depends on the column on the periodic table
