According to the Bohr model of a hydrogen atom, the frequency of light radiated by an electron moving from an orbit ₁ to an orbit n₂ corresponds to the energy level difference between ₁ and ₂ of where E = Eo ( − 2) - mez²4 32x²² Eo and where me is the electron mass, Z is the atomic number, e is the magnitude of the electron charge, is the permittivity of free space, and ħ is Planck's constnt divided by 27.

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.

If you are shining light on a Pt electrode and no electrons are emitted, what do you have to do to generate electrons? Decrease the wavelength of the light to increase the energy of the photons to emit electrons Electrons can not be emitted from Pt because like any other noble metal it does not react, even under light exposure (unlike other metals, e.g. Na, Sr or Cu) Increase the wavelength of the light to increase the energy of the photons to emit electrons Wait longer times or increase the intensity of the light source, since the energy of the absorbed light is not high enough to emit electrons from Pt surface
