The free-electron model of metals assumes that the outermost valence electrons of each atom are free to roam about the metal. In its simplest form, the metal is modeled as a box with zero potential energy inside and infinite potential energy outside. To describe the behavior of electrons in such a potential, we need to determine the allowed quantum states and how the electrons are distributed among those states. The number of quantum states available with energies

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
