A) in nucleus
B) in ground energy state
C) in first excited state
D) at infinite distance from the nucleus
Correct Answer: D
Solution :
Key Idea The energy of electron is given by \[{{E}_{n}}=\frac{13.6\,\,{{Z}^{2}}}{{{n}^{2}}}eV\]/atom where Z is atomic number. n is number of orbits. \[{{E}_{n}}\propto \left[ -\frac{1}{{{n}^{2}}} \right]\] Hence, as the value of n increases, energy of the electron also increases. Therefore, when n becomes infinite, energy also becomes infinite. Hence, due to this reason the maximum energy possessed by an electron, when it is present at infinite distance from the nucleus.You need to login to perform this action.
