The energy required to remove an electron from a surface of a solid element is called its work function. If a minimum of 431.3 kJ/mol is required to remove electrons from Cu atoms on a surface of a sample of copper, what is the maximum wavelength (λmax) of light that can remove an electron from a Cu atom on this surface? If the same copper surface is irradiated with light of λ=153.8 nm, what is the maximum kinetic energy that...
The energy required to remove an electron from a surface of a solid element is called its work function. If a minimum of 360.9 kJ/mol is required to remove electrons from Al atoms on a surface of a sample of aluminum, what is the maximum wavelength (max) of light that can remove an electron from an Al atom on this surface?
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...
- Why does it take energy to remove an electron from a metal surface? - Why are no electrons emitted from the surface of a metal if the frequency of light is below a threshold value? - How does application of the conservation of energy explain the dependence of electron kinetic energy upon the frequency of light shone on the metal surface. The subject is Physical CHEM ; Quantum mechanics
