Question

Five possible transitions for a hydrogen atom are listed below: Select whether the atom gains or loses energy for each transition.

Loses: ni = 6;nf = 3

Gains: ni = 5; nf = 7

Loses: ni = 4; nf = 3

Loses: ni = 7; nf = 3

Gains: ni = 2; nf = 6

Find the transition where the atom gains the most energy. How much energy does the atom gain? 3.02 eV You are correct. Your receipt no. is 161-84 Help: Receipt Previous Tries

Find the transition which will emit the shortest wavelength photon. What is the energy of the photon of this transition?

Explanation / Answer

For the shortest wavelength energy emitted should be maximum because wavelength is inveresely proportional to the energy emitted.

So, the mximum energy is transmitted for n=2 to n=6.

Energy of the photon of this transition= 3.02 ev
