Is energy absorbed when an electron moves to a closer shell?
No, energy is released when an electron moves to a closer shell. This process is known as an electron transition or recombination, and it typically results in the emission of light or other forms of electromagnetic radiation. The energy difference between the two shells is released in the form of a photon.
Thermionic Emission of electron is due to?
Thermionic emission of electrons is due to the heating of a metal, which causes electrons to gain enough thermal energy to overcome the work function of the metal and escape into free space. This process results in the emission of electrons from the metal surface.
How do different metals affect emission of electrons?
Different metals have different work functions, which determine the amount of energy required to remove an electron from the surface of the metal. Metals with lower work functions typically exhibit higher electron emission because it requires less energy to release an electron. Additionally, the surface properties of the metal can affect electron emission, such as roughness or cleanliness, which can impact the efficiency of the emission process.
Emissin of light from an atom occurs when an electron what?
Lots of wrong answers out there, tested this on school, the answer is: Drops from a higher to a lower energy level
What is the process in which an electron returns to a lower energy level and emits a photon?
This process is called "emission." When an electron transitions from a higher to a lower energy level within an atom, it releases a photon of light corresponding to the energy difference between the two levels. This emitted photon carries away the energy that the electron lost during the transition.
What is the excited state of phosphorus?
The excited state of phosphorus occurs when an electron is promoted to a higher energy level within its electron configuration. This results in phosphorus having more energy than in its ground state, which can lead to the emission of light or other forms of energy when the electron returns to its original energy level.
How does an electron must move in order to release a photon of light?
An electron must move from a higher energy level to a lower energy level within an atom in order to release a photon of light. This process, known as electron transition, results in the emission of light energy in the form of a photon.
What happens when an electron returns to its lower energy level?
When an electron returns to its lower energy level, it emits a photon of specific energy corresponding to the energy difference between the higher and lower levels. This process is called emission, and it results in the electron losing energy and returning to a more stable state.
Is energy absorbed when an electron moves to a closer shell?
No, energy is released when an electron moves to a closer shell. This process is known as an electron transition or recombination, and it typically results in the emission of light or other forms of electromagnetic radiation. The energy difference between the two shells is released in the form of a photon.
Thermionic Emission of electron is due to?
Thermionic emission of electrons is due to the heating of a metal, which causes electrons to gain enough thermal energy to overcome the work function of the metal and escape into free space. This process results in the emission of electrons from the metal surface.
How does quantum theory explain the emission spectra of atoms?
Quantum theory explains the emission spectra of atoms by proposing that electrons in atoms can only exist in specific energy levels. When an electron moves from a higher energy level to a lower one, it emits a photon of light with a specific energy corresponding to the difference in energy levels. This results in the unique emission spectra observed for each element.
How do different metals affect emission of electrons?
Different metals have different work functions, which determine the amount of energy required to remove an electron from the surface of the metal. Metals with lower work functions typically exhibit higher electron emission because it requires less energy to release an electron. Additionally, the surface properties of the metal can affect electron emission, such as roughness or cleanliness, which can impact the efficiency of the emission process.
Emission of light from an atoms occurs when an electron?
falls from a higher energy state to a lower energy state.
Emissin of light from an atom occurs when an electron what?

The emission of a positron also results in the creation of a?
When an atomic nucleus releases a positron, it has undergone beta plus decay. This nuclear transformation event also will release a neutrino. Use the link below for more information.
Why does excited hydrogen atoms always produce the same line emission spectrum?
Excited hydrogen atoms produce the same line emission spectrum because they have specific energy levels associated with their electron transitions. When an electron falls from a higher energy level to a lower one, it emits a photon with a specific energy, corresponding to a specific wavelength of light. This results in the characteristic line emission spectrum of hydrogen.
What is the process in which an electron returns to a lower energy level and emits a photon?
This process is called "emission." When an electron transitions from a higher to a lower energy level within an atom, it releases a photon of light corresponding to the energy difference between the two levels. This emitted photon carries away the energy that the electron lost during the transition.
