By Thomson's time, it was known that excited atoms emit light
waves of only certain frequencies. In his model, the frequency of
emitted light is the same as the oscillation frequency of the
electron or electrons in the atom. What would the radius of a
Thomson-model atom have to be for it to produce red light of
frequency 4.63×1014 Hz ? (see Appendix F from the
textbook for data about the electron)

An excited hydrogen atom emits light with a wavelength of 397.2 nm to reach the energy level for which n = 2. In which principal quantum level did the electron begin? It would be very helpful if the last step could be over explained, thats where my answer is going wrong.

A Rydberg atom is one in which an electron is in a very high excited state (n 40 or higher). Such atoms are useful for experiments that probe the transition from quantum- mechanical behavior to classical. Furthermore, these excited states have extremely long lifetimes (i.e., the electron will stay in this high excited state for a very long time). A hydrogen atom is in the n47 state. (a) What Is the lonization energy of the atom when it is in...

Which of the following electron configurations is not possible for an atom in an excited state?...
Which of the following electron configurations is not possible for an atom in an excited state? I know the answer is D but I do not understand how E is possible since 4s14 would mean 14 electrons in an s orbital. Doesn't that exceed the limit of 2???

Calculate the wavelength of light (in nanometers) emitted from a hydrogen atom if the electron is initially in the n=4 excited state shell and drops directly to the n=2 shell; that is, a 4→2 transition. You will need the value of the Rydberg constant which is 2.178 x 10-18 J, Planck's constant which is 6.626 x 10-34 J·s, and the speed of light which is 3.00 x 108m/s. a. 365 b. 487 c. 209 d. 337
