A) in nucleus
B) in ground energy state
C) in first excited state
D) at infinite distance from the nucleus
Correct Answer: D
Solution :
As we know that\[{{E}_{n}}\propto \left[ -\frac{1}{{{n}^{2}}} \right],\]where n is the number of orbit. Hence, as the value of n increases, energy of the electron also increases. Hence, when n becomes infinite, energy also becomes infinite. Hence, due to this reason maximum energy is possessed by an electron, when it is persent at infinite distance from the nucleus.
