An electron in the ground state of a hydrogen atom (-13.6 eV) absorbs a 10.2 eV photon and jumps to the first excited state. What is the energy in eV of the first excited state?
4. When a hydrogen atom is bombarded, the atom may be raised into a higher energy state. As the excited electron falls back to the lower energy levels, light is emitted. What are the three longest-wavelength spectral lines emitted by the hydrogen atom as it returns to the n = 1 state from higher energy states? Give your answers to three significant figures. The lowest possible state, n = 1, corresponds to the electron in its smallest possible orbit; it...

Electrons in an unknown atom(not hydrogen) are excited from the ground state to the n=3 energy level. As these electrons make quantum jumps back to the ground state, photons of three different energies are emitted. The most energetic photon has an associated wavelength of 62.2 nm and the least energetic photon has an associated wavelength of 207 nm. What is the associated wavelength of the other type pf photon? The answer is 3-1 (20 eV), 3-2 (6 eV) and 2-1...
