# Question

Does a photon of visible light (l = 400 – 700 nm) have sufficient energy to excite an electron in a hydrogen atom from the n = 1 to the n = 5 energy state? From the n = 2 to the n = 6 energy state?

## Answer to relevant Questions

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? The Heisenberg uncertainty principle can be expressed in the form where E represents energy and t represents time. Show that the units for this form are the same as the units for the form used in this chapter: Discuss what happens to the energy levels for an electron trapped in a one-dimensional box as the length of the box increases. Which of the following sets of quantum numbers are not allowed in the hydrogen atom? For the sets of quantum numbers that are incorrect, state what is wrong in each set. a. n = 3, ℓ = 2, mℓ = 2 b. n = 4, ℓ = 3, mℓ = ...The relative orbital levels for the hydrogen atom can be represented as Draw the relative orbital energy levels for atoms with more than one electron, and explain your answer.
