Question

in excited h atom electron return from 7 energy level to ground state in4 hydrogen atom find the maximum number of photons that can be emitted during dexcitening​

Answer 1

Answer:

ALL OF THESE ENERGY TRANSITIONS ARE POSSIBLE:

4–3

4–2

4–1

3–2

3–1

2–1

BUT ONLY THREE PHOTONS MAXIMUM CAN BE EMITTED:

4–3

3–2

2–1

Answer 2

Answer:

When the excited electron of an H atom in n =6 drops to the ground state, the following transitions are possible: Hence, a total numberof (5 + 4 + 3 + 2 + 1) 15 lines will be obtained in the emission spectrum.
