Electrons in stable orbits actually have negative energies since the energy is binding. If the n = 1 energy of hydrogen corresponds to -13.6 eV, and the n = 3 level is -1.5 eV. What is the frequency of a photon emitted as it transitions from the n = 3 to the n = 1?

Consider the energy levels for Hydrogen in the table below: (note the energy is relative to the energy necessary for an electron to escape. So for Level n = 1 the electron would need to gain 13.6 electron volts to no longer be negative and thus able to escape the atom!) Level (n = ) Energy (in eV) 1 -13.6 2 -3.40 3 -1.51 4 -0.850 5 -.544 6 -.378 What would be the energy of a photon emitted when...

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...

An electron in hydrogen transitions from n = 5 to n = 1. Was a photon absorbed or emitted by this electron? (Since the electron "jumped" down to a lower energy level, it must have lost energy, so a photon was emitted.) Find the energy of the photon. (13.1 eV) Find the photon's energy in joules. (2.10times 10^-18 J) Find the momentum of the photon. (7.00 times 10^-27 kg. m/s) Find the wavelength of this photon. (94.7 nm)
