A) \[-5.40\,eV\]
B) \[~-2.72\,eV\]
C) \[~-\text{ }0.85\text{ }eV\]
D) \[~-\text{ }0.54\text{ }eV\]
Correct Answer: D
Solution :
Energy in ground state \[{{E}_{1}}=-13.6\,eV\] Energy level\[n=5\] (given) The energy of hydrogen atom at level 5, is \[{{E}_{5}}=-\frac{13.6}{{{n}^{2}}}=\frac{13.6}{{{5}^{2}}}=\frac{13.6}{25}\] \[=0.54\,eV\]You need to login to perform this action.
