How Photoelectric Effect Depends on Atomic Number?
A phenomenon in which electrons are emitted when electromagnetic radiation hits a material is defined as the Photoelectric effect.
The amount of energy required to eject the electron from an atom is directly dependent on the atomic number.
The number of protons in the atomic nucleus is defined as an Atomic number.
The photoelectric effect occurs because electrons tend to absorb energy from the incident light.
The energy absorbed is used to overcome the forces that bind them to the nuclei of the metal.
The amount of absorbed radiation, in turn, depends on the energy of the incident photons, which are capable of exciting electrons.
Thus, an increased atomic number increases the possibility of the photoelectric effect.
Gilbert Lewis also stated that larger atomic numbers mean a greater probability that a photoelectric event will occur.
The wavelength of light determines how many electrons are emitted.
Thus the photoelectric effect confirms that electromagnetic radiation is related to an element's atomic structure.
Planck's equation shows that the photoelectric effect is also dependent on the frequency of light.
