The energy of third orbit of Li ²⁺ ion (in J ) is

Options

  1. A-2.18 10⁻¹⁸
  2. B-6.54 10⁻¹⁸
  3. C-7.3 10⁻¹⁹
  4. D+2.18 10⁻¹⁸

Correct answer

A. -2.18 10⁻¹⁸

Step-by-step solution

Energy ( E _ n )=-2.18 10⁻¹⁸ ( z ^2 n ^2 ) J Z=3 n =3 (third orbit) E₃=-2.18 10⁻¹⁸ (3)^2 (3)^2 JE₃=-2.18 10⁻¹⁸ ~J
