9. (15 points) Electrons are emitted from the surface of a metal when it's exposed to light. This is called the photoclectric effect. Each metal has a certain threshold frequency of light, below which nothing happens. Right at this threshold frequency, an electron is emitted. The binding energy of a metal is the minimum amount of energy required to remove an electron from the surface of the metal. The binding energy for lithium metal is 279.7 kJ/mol (that is, it...
