Question:medium

The ground state energy of the Hydrogen atom is approximately:

Show Hint

The energy levels of hydrogen decrease as \( 1/n^2 \): - Ground state (\( n=1 \)): \( -13.6\text{ eV} \) - First excited state (\( n=2 \)): \( \frac{-13.6}{4} = -3.4\text{ eV} \) - Second excited state (\( n=3 \)): \( \frac{-13.6}{9} \approx -1.51\text{ eV} \)
