If n is the orbit number of the electron in a hydrogen atom, the correct statement among the following is 

Options

A. electron energy increases as n increases.
B. hydrogen emits infrared rays for the electron transition from `n = oo` to `n=1`
C. electron energy is zero for `n = 1`
D. electron energy varies as `n^(2)`.

Answer

A

Explanation

In a hydrogen atom, the energy of electron in `n^("th")` orbit is `E_(n)==-(13.6)/(n^(2))eV`
