Classify each of the following statements as True or False. Light source B has energy as is seen by the electrons emitted from the surface of the sodium metal, but light source A has no energy. The sodium metal has enough energy to absorb the energy of light source A, but does not have enough energy to absorb the energy of the light source B. Light source A does not have enough energy to cause electrons to be emitted from the surface of the sodium metal, but light source B does. Light source A has a shorter wavelength than light source B and therefore cannot cause electrons to be emitted from the surface of the sodium metal. --

Quantum Chemistry

Quantum chemistry deals with the properties of chemical systems and their reactions. The branch of chemistry which is more concerned with quantum chemistry is physical chemistry. It is a more sophisticated field of theoretical physics which is concerned towards the application of physical concepts towards various chemical aspects such as, formation of atoms, chemical structure descriptions, chemical bond strength, hybridization, conjugation etc. Quantum chemistry mainly studies the various states i.e., ground state, excited state, transition states of the individual atoms or molecules taking place during any chemical reaction. The laws of motion explained by various scientists, which are termed as “classical mechanics” were not acceptable in terms of electrons, protons, atoms, light etc. Thus, a new theory named “quantum mechanics” emerged to understand the basic framework of various atomic and subatomic particles.

Question

100%

Classify each of the following statements as True or False.
Light source B has energy as is seen by the electrons emitted from the surface of the sodium metal, but light source A
has no energy.
The sodium metal has enough energy to absorb the energy of light source A, but does not have enough energy to
absorb the energy of the light source B.
Light source A does not have enough energy to cause electrons to be emitted from the surface of the sodium metal, but
light source B does.
Light source A has a shorter wavelength than light source B and therefore cannot cause electrons to be emitted from
the surface of the sodium metal.

When light source A of a particular color is directed toward the surface of a piece of sodium
metal, the result is that no electrons are emitted from the metal surface.
When light source B of a different color is directed toward the surface of a piece of sodium
metal, the result is that electrons are emitted from the surface of the metal.
