All transitions in which electrons move from a lower to a higher level require a gain of energy. example: 2nd to 3rd shell
Any electron is not fixed to any sub-shell or orbital. If you provide sufficient energy to an electron, it would make transition to any of the higher energy orbitals and then come back to the lower orbitals radiating energy.
Electron affinity is the energy released when an atom gains an electron to form a negative ion, while electron gain enthalpy is the enthalpy change accompanying the addition of an electron to a gaseous atom. Electron affinity is a specific term used in the context of forming an ion, while electron gain enthalpy is a general term for the enthalpy change associated with gaining an electron.
The first ionization energy of a nonmetal is typically high since nonmetals have a strong attraction for electrons due to their high electronegativity. Nonmetals tend to gain electrons to achieve a stable electron configuration, making it energetically unfavorable to remove an electron, resulting in a high ionization energy.
Chlorine has a high electron affinity due to its tendency to gain an electron to achieve a stable electron configuration. It also has a relatively low ionization energy, meaning it takes less energy to remove an electron from a chlorine atom compared to other elements.
When electrons gain energy, they move to higher energy levels or orbitals further away from the nucleus of the atom. This is known as electron excitation.
the electron will gain energy
Any electron is not fixed to any sub-shell or orbital. If you provide sufficient energy to an electron, it would make transition to any of the higher energy orbitals and then come back to the lower orbitals radiating energy.
The additional potential energy the reactants must gain in order to react
The electron gain enthalpy of hydrogen is approximately -72.8 kJ/mol, indicating that it releases energy when gaining an electron. In contrast, the electron gain enthalpy of phosphorus is approximately -78.6 kJ/mol, showing a larger energy release when phosphorus gains an electron due to its higher electronegativity.
Electron Gain Enthalpy is the amount of Energy released when an isolated gaseous atom accepts an electron to become a monovalent gaseous anion.For Example:Atom(gas) +Electron ---->Anion(gas) +Energy(Electron Gain Enthalpy)

Atoms of group 17 elements (halogens) give off energy in the form of light when they gain electrons. This process is known as electron capture, which releases energy as the electron moves to a lower energy level.
it lose a hydrogen ion and one electron
Inert gases are the most stable ones, so if we try to add another electron, the stable electronic configuration is disturbed. So, we have supply energy for this process. Hence, electron gain enthalpy is positive.
Chlorine has a high electron affinity due to its tendency to gain an electron to achieve a stable electron configuration. It also has a relatively low ionization energy, meaning it takes less energy to remove an electron from a chlorine atom compared to other elements.
