Question

Number of possible spectral lines which may be emitted in bracket series in H atom sample,if electron are de exited from 9th excited state to ground state are

Answer 1

hii dear....

here is ur answer

Answer:

The number of possible spectral lines that may be emitted in the Brackett series in H atom, if electrons present in 9th excited level returns to ground level, is 5.

The transitions are 9→4,8→4,7→4,6→4 and 5→4 respectively.

Answer 2

Five spectral lines can be emitted in bracket series in H atom if electrons are exited from 9th excited state to ground state.

• We get the bracket series of hydrogen atoms in the far infra-red region.
• The five transitions are from 9⇒4, 8⇒4, 7⇒4, 6⇒4, and 5⇒4
• These spectral lines are formed from transitions of electrons from one state to another state.
• There is the emission or absorption of energy in the form of light whenever a transition is taking place.
• Spectral lines give information about the temperature, frequency of the atom undergoing emission.
