Electrostatic potential energy

Postby Riya Shah 4H » Fri Oct 19, 2018 9:47 pm

What is the significance of the equation E is directly proportional to q1q2/r ?

One thing is that the equation reflects the inverse relationship between E (electrostatic potential energy) and r (distance between charges). This relationship demonstrates how the inner e- shield outer e- from the electrostatic attraction of the positive nucleus ∴ outer e- feel a reduced electrostatic attraction, which results in an effective nuclear charge. This is why s-electrons have a lower energy than p-electrons in the same shell and within a shell the order is: s < p < d < f.
