Bohr's model for the Hydrogen atom m problems 22 - 28. (Be careful with signs here. Signs are important and the wrong sign means the wrong answer.) 22. | 1 Point] Calculate the orbital radius ( in run) of the electron in the ground state. 23. [1 Point] Calculate the PE ofthe electron in this ground state {in eV}. 24. [1 Point] Calculate the KB of the electron in the ground state (in eV). 25. [I Point] What is the total energy of the electron in this ground state (in e'v'}? 26. [1 Point] You want to excite an electron in the ground state to the n = 3 level. What is the minimum kinetic energy (in eV] that a free electron colliding with an atom needs to have to do this? 27. [1 Point] What is the orbital radius in nm of the electron when it's at this higher level? 28. [1 Points] If an electh drops down from the n = a level to the n = 2 leveL and then to the ground state of hydrogen, what colors of light will be emitted? (a) Photon color for n = 6 to n = 2 jump (in urn]? {b} Photon color for n = 2 to ground state jump { in mm)
