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` orbits is
`E_(n) = (13.6)/(n^(2)) eV`
From the above expression it is clear that electron energy increases as n increases.
