Question

when the electron of 5th Orbit jump into the first orbit the number of spectral line produced in hydrogen spectrum is

Answer 1

Answer:

Explanation:

When electron jumps from 5th orbit to 2nd these spectral lines produced  

1.5→2 transition

2.5→3 transition

3.5→4 transition

4.4→2 transition

5.4→3 transition

6.3→2 transition

So there are 6 spectral lines are produced

Answer 2

When the electron of the 5th Orbit jumps into the first orbit the number of spectral lines produced in the hydrogen spectrum is 10.

• Electrons jump from a higher level to a lower level and energy is released.
• The jumping of electrons from lower to higher levels absorbs energy.
• The number of spectral lines produced is calculated by the formula- $\frac{(n2 - n1)(n2 - n1 + 1)}{2} = \frac{(5 - 1)(5 - 1+ 1)}{2} = \frac{5 \times 4}{2} = 10$.
• Here, n2 and n1 are lower and higher energy levels respectively.
• Transition is from 5-2, 5-3,5-4,5-1, 4-3,4-2,4-1,3-3,3-1,2-1.
