Question 514: Atoms & Nuclei

Question

The electron in hydrogen atom is initially in the third excited state. When it finally moves to ground state, the maximum number of spectral lines emitted are

Accepted Answer

Initially the electron is in the third excited state i.e. n = 4. Hence we can have transitions :
$$4	o3,4	o2,4	o1$$
$$3	o2,3	o1$$
$$2	o1$$
Hence, six transitions are possible.
