The electron affinity (or electronegativity as it would more usually be called) of an atom typically depends on the number of electrons in the outer shell. It is also influenced by the size of the atom. One electron in the outer shell gives you a low electronegativity, and seven electrons in the outer shell gives a high electronegativity; eight gives zero electronegativity. And as atoms get larger, the electronegativity falls off. So the very highest electronegativity is for the fluorine atom which is the smallest atom that has seven electrons in its outer shell.

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 value of different electron affinity will give you an ionic bond?

An ionic bond forms when there is a large difference in electron affinity between two atoms. Typically, one atom has a high electron affinity (strongly attracts electrons) and the other atom has a low electron affinity (weakly attracts electrons), leading to the transfer of electrons from one atom to the other to form charged ions that are held together by electrostatic forces.


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.


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.


How is electron affinity from electronegative?

Electronegativity is the measure of pull one atom has on another. Electron affinity is the amount of energy that is released when a neutral atom gains an electron.


Does high value of electron affinity for an atom means that it will gain electron easily?

Yes, that is part of the definition of electron affinity.


How is electron affinity different from electronegativity?

Electronegativity is the measure of pull one atom has on another. Electron affinity is the amount of energy that is released when a neutral atom gains an electron.


Does electron affinity gain electrons?

Yes. Electron affinity is the process by which a neutral atom gains an electron and the EA is the measure of energy released. The resulting ion will be negative.


How is affinity different from electronegativity?

Electronegativity is the measure of pull one atom has on another. Electron affinity is the amount of energy that is released when a neutral atom gains an electron.


Which has the lower electron affinity germanium or selenium?

Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion. In general, electron affinity tends to decrease as you move down a group in the periodic table, which is why selenium has a lower electron affinity than germanium.


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.


What is the difference between electron affinity and electron gain enthalpy?

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.
