The energy (in J) released when an excited electron of 5^ th orbit of hydrogen atom returns to its ground state is

Options

  1. A2.091 10⁻¹⁸
  2. B4.182 10⁻¹⁸
  3. C6.273 10⁻¹⁸
  4. D8.364 10⁻¹⁸

Correct answer

A. 2.091 10⁻¹⁸

Step-by-step solution

aligned & E =2.18 10⁻¹⁸ ( 1 n ₁^2 - 1 n ₂^2 ) & =2.18 10⁻¹⁸ ( 1 5^2 - 1 1^2 )=2.18 10⁻¹⁸(-0.96) & =-2.091 10⁻¹⁸ ~J aligned
