In van der walls crystals, there exists a high degree of stability of the outer electron shell.
Answer: A
This is the reason for chemical inactivity in these crystals.
An atom of a rare gas is placed is an electric field E. Then
Answer: A
For equilibrium nucleus is shifted in the direction of E by an amount which is proportional to E.
Assertion (A): A capacitor with imperfect dielectric can be represented by a capacitance in parallel with resistance.
Reason (R): For imperfect dielectrics, dielectric constant has real and imaginary parts.
Answer: A
Imaginary part of dielectric constant is responsible for dielectric losses.
