vinter said:No they don't include the work function.
Ionization potential is defined as the energy required to remove the outermost electron from an isolated atom in gaseous state.
An isolated atom in gaseous state does not have any work function.
Work function arises from other factors including the crystal structure etc. etc.
Ionization potential is the amount of energy required to remove an electron from an atom or molecule in its ground state. It is typically measured in electron volts (eV) or kilojoules per mole (kJ/mol).
The ionization potential of an atom is directly related to the number of protons in the nucleus and the number and arrangement of electrons in the atom's energy levels. The higher the number of protons and the closer the electrons are to the nucleus, the higher the ionization potential will be.
The ionization potential of an atom or molecule determines its reactivity and ability to form chemical bonds. Atoms with low ionization potentials are more likely to lose electrons and form positive ions, while atoms with high ionization potentials are more likely to gain electrons and form negative ions.
Work function is the minimum amount of energy required to remove an electron from the surface of a solid material. It is a measure of the strength of the bond between the electrons and the material's surface.
The higher the work function of a material, the more energy is required to remove an electron from its surface. This means that materials with high work functions require more energy to emit electrons, making them less likely to emit electrons compared to materials with lower work functions.
