18.( 5 points) Determine the energy change associated with the transition from n -5 in the hydrogen atom. What is the wavelength of this photon? (7.21) 2 to n
What is the change in energy ΔEΔEDeltaE of the hydrogen atom as the electron makes the transition from the n=3n=3 energy level to the n=1n=1 energy level? Express your answer numerically in electron volts.
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...
