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 tranition from `n=prop` 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`
