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

Options

  1. A3
  2. B4
  3. C5
  4. D6

Correct answer

D. 6

Step-by-step solution

Initially the electron is in the third excited state i.e., n =4 Hence maximum number of spectral lines emitted = n ( n -1) 2 = 4(4-1) 2 =6
