In chemistry you learned that a hydrogen atom has an ionization energy of 13.6 eV. Restate this using the physics concepts we’ve been studying in our course (for example, use the language of “electrostatic force,” “work,” “electric potential energy” etc. instead of “ionization energy,” which is a chemistry term).
The ionization potential of a hydrogen atom is 13.6 eV. How does this compare to the energy of a typical particle at the recombination epoch, when the temperature of the universe was 3000 K. How does that compare to the energy of photons at the peak of the Planck function at that time? What can you conclude from these comparisons?
For the hydrogen atom, its energy at ground state is 13.6 eV, at first excited state is 3.4 eV at second excited state is 1.5 eV and at the third excited state is 0.85 eV. i) Give the energy value for the first two states in Joule (J). [1eV =1.6 x 10-19 J] (2 marks) ii) With the aid of schematic diagram, determine the energy of emitted photon when the atom jumps from the first and third excited states to...

The electron in hydrogen atom absorbs a photon with an energy of 13.6 eV. The electron decays to its energy level of 3.4 eV. What is the energy of the photon it emits? (Planck's constant is 4.14 x 10^-15 eVs. What is the frequency of that proton? What is the corresponding wave length of that proton? Thanks for the help ...I know it is a loaded question but I am lost!
