Question

The angular momentum and the energy of the electron in the second Bohr’s orbit are respectively

• A. \( \frac{h}{\pi} \) and -13.6 eV
• B. \( \frac{2h}{\pi} \) and -1.5 eV
• C. \( \frac{h}{\pi} \) and -3.4eV
• D. \( \frac{h}{2\pi} \) and - 3.4 eV
• E. \( \frac{2h}{\pi} \) and -3.4 Ev

Hint:

Memorize the energy levels of Hydrogen for quick calculations:
\(n=1 \to -13.6 \text{ eV} \)
\(n=2 \to -3.4 \text{ eV} \)
\(n=3 \to -1.51 \text{ eV} \)
\(n=4 \to -0.85 \text{ eV} \)
