What is energy released on adding an electron to an isolated gas phase atom?

All electron shells represent an energy level - it doesn't matter if its the outermost shell or not.
In order for there to be a release of energy the electron has to be coming from a higher energy state. The only energy state higher than the outer-most electron shell would be a free electron.
The only way an electron becomes a free electron is that sufficient was provided to lift it from what-ever electron shell (energy level) it was previously in to escape velocity. The energy that it then releases in returning is then this exact same amount of energy.

∙ 9y agoEnergy is released when an electron is added to a neutral gaseous atom due to electron affinity. It refers to the change in energy when a neutral atom bonds with an electron.

∙ 12y agoThe atom becomes negatively charged because it has extra electrons. In short, the atom ionizes.

What is electron gen enthalpy?
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)
What does adding one 2s electron for Lithium do to the energy of the 2 p electrons Why does this make sense?
Lithium belongs to atomic number 3 adding 1 electron in the energy shell does not make sense because it will still be unstable.
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
Why oxygen is having two electron affinity?
First EA is usually exothermic as energy is released when the nucleus attarcts an electron is larger than the energy taken in to overcome their inter-electronic repulsion. Second EA is always endothermic since electron is added to a negative ion. Energy is needed to overcome the repulsion between the two negatively charged species.
What happens to an electron during an electron transition?
Drops to a lower energy level and emits one photon of light.
What is the meaning of a negative value for the electron affinity of an atom?
Electron affinity is the amount of energy required to remove an electron from an atom. Or an energy released by adding an electron to a gaseous atom ( ie, negative quantity). In this case, if an element has a negative Electron Affinity, its indicating that this element is stable than the neutral ones.

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)
When an electron drops to a lower energy level what is the energy of a photon released?
The energy of the photon is the same as the energy lost by the electron

When an electron drops from a higher energy level to a lower energy level is it taken from the environment?
No, the energy released by electron might be taken by enviornment. Electron remains in the infuence of corresponding nuclei, in another energy level.
What is meant by isolated gaseous atom and why this term is used in case of ionization energy?
ionization enthalpy means the energy required to remove an electron from isolated gaseous atom in its ground state . the isolated gaseous state is the state in which no other force of attraction acting on an atom form other atom . so that, we get the exact energy required to romove or add an electron to an atom. and here ground state is used to say that electron are stable and are not exited .. so , the ionization enthalpy is the energy required to remove an electron from gaseous atom which is free from other atom in that state in which electrons are stable. by shashank
Where does an electron move after a photon is released?
lower energy level
What is the amount of energy released by an electron as it returned to ground state?
An excited electron releases a photon as it returns to ground state.
Why electron affinity of fluorine is large?
Electron affinity of an element is defined as the energy released by adding an electron to a gaseous atom of the element. With the electronic configuration of the fluroine atom being [Ne] 2s2 2p5, it needs just one more electron to form the fluoride ion (F-) which has the noble gas structure and is much more stable.
What part of the atom is able to be lost or gained?
the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.
