**Activity: Calculating Energy Levels in a Hydrogen Atom**

A hydrogen atom is initially in state \( N = 3 \), where \( N = 1 \) represents the lowest energy state (ground state). Determine the total energy (\( K+U \)) in electron volts (eV) for this atomic hydrogen energy state.

\[ E_3 = \] _______ eV

Next, the hydrogen atom transitions to state \( N = 2 \). Calculate the total energy (\( K+U \)) in electron volts (eV) for this lower atomic hydrogen energy state.

\[ E_2 = \] _______ eV

Finally, find the energy, in electron volts, of the photon emitted during the transition from level \( N = 3 \) to \( N = 2 \).

\[ E_{\text{photon}} = \] _______ eV

**Note:** Filling these blanks requires knowledge of electron energy level calculations, specifically using the Bohr model for hydrogen.
