A hydrogen atom falls from n ^ th higher energy orbit to first energy orbit ( n =1 ). The energy released is equal to 12.75 ev . The n^ th orbit is

Options

  1. An=4
  2. Bn=3
  3. Cn=6
  4. Dn=5

Correct answer

A. n=4

Step-by-step solution

In hydrogen atom, aligned & E =13.6 ( 1 n ₁^2 - 1 n ₂^2 ) & 12.75=13.6 ( 1 1^2 - 1 n ^2 ) & n =4 . aligned
