An atom is in ground state if: Select one: a. One or more electrons are excited to higher energy levels b. The atom is stable due to having only filled electron shells (noble gas configuration). c. Its electrons reside in the lowest possible energy levels d. None of the other options. e. Its lowest energy level is filled. Which statement is true and can be explained by the wave-particle duality of electrons? Select one: a. When electrons transition from a higher energy level to a lower energy level, they are expelled from the atom as a photon of light. b. Light waves can interact to produce diffraction patterns, but electrons do not display this property. c. None of the other options. d. Electrons have a charge of-1 relative to a proton. O e. Electrons exist in discrete energy levels because their wave-like properties are described by the Schrödinger equation, which has discrete solutions Which of the following best describes the wave-particle duality of light? Select one: O a. Electrons and photons have no properties in common. b. None of the other options. c. The photoelectric effect provides evidence that the energy of a photon in a beam of light is proportional to the intensity of the light. d. Particles have wave-like properties, but exclusively on the atomic level (i.e. an electron, but not an elephant, would be an example of a particle with wave-like properties). e. Photons of light exhibit both wave-like and particle-like properties, depending on the environment with which they interact.
