- n = 5 n = 4 3. Refer to the illustration on the right. In a set of experiments on a hypothetical one-electron atom, you measure the wavelengths of the photons emitted from transitions ending in the ground state (n=1). You also observe that it takes 15 eV to ionize this atom. (a) What is the energy of the atom in each of the levels (i.e. n=1, n=2, n=3, n=4, n=5)? (b) If an electron made a transition from the n=4 to the n=2 level, what wavelength of light n = 3 n = 2 would it emit? n = 1 A = 73.86 nm A = 75.63 nm A=79.76 nm A = 94.54 nmarrow_forwardAn electron in a hydrogen atom transitions from the n=5 state to the n=1 state, emitting a photon. a.

Round your answer to 2 significant figures. Add your answerarrow_forwardThe following diagram shows the complete set of orbitals of a hypothetical atom. The yellow circle represents the nucleus. Point D represents a location beyond the orbitals of this particular atom. Which of the following statements about an electron transitioning among the labeled points is TRUE? с D An electron transitioning from orbital A to orbital B will emit or absorb light with a longer wavelength than an electron transitioning from orbital B to orbital A. O The energy difference between orbitals B and C is bigger than that between orbitals A and B. To transition to a point between orbital A and B, an electron would need to absorb less energy than the difference between the energies of orbital A and B. An electron transitioning from orbital B orbital C would absorb green light. To transition from orbital C to orbital B, an electron must emit light.arrow_forwardD1.
