Question

Is equilibrium position of the electron at the center of the nucleus. Explain why.

Answer 1

Yes:

the equilibrium position of the electron is at the center of nucleus. In the atomic model , the nucleus has positive charge while the electron carry a negative charge. we know that unlike charges attaract each other. so nucleus attaract the electron towards it.the electron will experience force in inward direction and will be unstable.due to the force , the electron moves towards center , and as it moves closer and closer, its stability increase.and force on it also increase.once it reach the center, the electric field will be zero and hence the electron will not be under any force. that marks the stability point for the electron
