5a. Quantum Flashcards
1
Q
The electron volt
A
The work done on a single electron when it is moved through a potential difference of 1 volt.
2
Q
Work Function
A
The minimum energy required to lift a Photo electron from the surface of a metal.
3
Q
Excitation
A
Where an electron is raised to a higher energy level in the shells of an atom.
4
Q
The photoelectric effect
A
Where a single photon interacts with a single electron to lift it from the conduction band of a metal.
5
Q
De Broglie wavelength
A
The wavelength of a particle at speed exhibiting wavelike properties.
6
Q
Threshold frequency
A
The frequency of light above which photo electrons may be created.
7
Q
Ground state
A
The lowest energy state an electron can occupy.
8
Q
Ionization energy
A
The energy required to remove an electron from the ground state.
