Is the process of electron affinity endothermic or exothermic?
The process of electron affinity is generally exothermic, meaning it releases energy.
Is the process of electron affinity exothermic or endothermic?
The process of electron affinity is generally exothermic, meaning it releases energy.
Is the process of electron affinity for an atom generally considered to be endothermic or exothermic?
The process of electron affinity for an atom is generally considered to be exothermic.
Why are electron affinity values for the noble gases endothermic?
Electron affinity values for noble gases are endothermic because these elements have stable electron configurations and do not readily accept additional electrons. This makes it energetically unfavorable for them to gain an extra electron, resulting in a positive electron affinity value.
Is ionization energy exothermic?
Ionization energy is the energy required to remove an electron from an atom. It is an endothermic process because energy is needed to overcome the electrostatic force holding the electron to the nucleus.

What energy changes when a neutral atom gains an electron?
When an electron is acquired by a neutral atom, the energy change is called electron affinity. Neutral atoms with an s2p6 electron configuration in the highest energy level are best classified as gases.
Is ionization energy exothermic?
Ionization energy is the energy required to remove an electron from an atom. It is an endothermic process because energy is needed to overcome the electrostatic force holding the electron to the nucleus.
Why electron affinity of dinegative ion is endothermic?
When an electron is added to a dinegative ion, it is already in a very stabilized state due to the presence of two extra electrons. Adding another electron would result in electron-electron repulsions and destabilize the system, requiring energy input. This leads to an endothermic process for adding an electron to a dinegative ion.
Why does electron affinity tend to become more exothermic as you move right across a period?
Electron affinity tends to become more exothermic as you move right across a period because the effective nuclear charge increases, leading to a stronger attraction between the nucleus and the incoming electron. This results in a more stable electron configuration and a release of energy.
Is ionization an exothermic or endothermic process?
Ionization is typically an endothermic process because energy is required to remove an electron from an atom or molecule, resulting in the formation of ions. This energy requirement is necessary to overcome the attractive forces between the positively charged nucleus and the negatively charged electron.
Definition of electron affinity?
The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
What is the equation for the electron affinity of Mg plus?
If you express your answer as a chemical equation with all forms given, you would get: Mg+(g) + e- -> Mg (g)
What element has no electron affinity?
Helium has no electron affinity.
