Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Energy of a van der Waals interaction as two atoms approach each other. The energy is "most favorable" at the van der Waals contact distance. Owing to electron–electron repulsion, the energy rises rapidly as the distance between the atoms becomes shorter than the contact distance. van der Waals Interactions: The basis of a van der Waals interaction is that the distribution of electronic charge around an atom fluctuates with time. 😎
