The angular momentum of an electron moving in an orbit of hydrogen atom is 1.5 ( h ) . The energy in the same orbit is nearly

Options

  1. A-1.3 eV
  2. B-1.4 eV
  3. C-1.5 eV
  4. D-1.6 eV

Correct answer

C. -1.5 eV

Step-by-step solution

Angular momentum of electron moving in n^ th orbit of hydrogen atom Hence, n=3 Now, energy of electron in 3^ rd orbit aligned E & = -13.6 z^2 n^2 & = -13.6 1^2 3^2 & =-1.51 eV & -1.5 eV aligned
