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

Answer»

electron energy increases as N increases.
hydrogen emits INFRARED rays for the electron tranition from `n=prop` to `n=1`.
electron energy is zero for `n=1`.
electron energy VARIES as `n^2`.

Solution :In a hydrogen ATOM, the energy of electron in `n^(th)` orbit is `E_n=-(13.6)/(n^2)eV`
