The ratio of kinetic energy to the total energy of an electron in a Bohr orbit of the hydrogen atom, is

  1. \( 1 : 1 \)
  2. \( 1 : -1 \)
  3. \( 2 : -1 \)
  4. \( 1 : -2 \)

Correct answer · Option 2

\( 1 : -1 \)

Explanation

Kinetic energy \( K = -\frac{1}{2} \) (Total energy \( E \)), hence the ratio of kinetic energy to total energy is \( 1 : -1 \).
