The 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.
