A) Electron energy increases as n increases.
B) Hydrogen emits infrared rays for the electron transition from \[n=\infty \] to \[n=1\].
C) Electron energy is zero for \[n=1\].
D) Electron energy varies as \[{{n}^{2}}\].
Correct Answer: A
Solution :
: In a hydrogen atom the energy of electron in \[{{n}^{th}}\] orbit is \[{{E}_{n}}=-\frac{13.6}{{{n}^{2}}}eV\] From the above expression it is clear that electron energy increases as n increases.
