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.

Why would flurine have the highest electron affinity?
Fluorine does not have the highest electron affinity it has highest electronegativity the highest electron affinity is for chlorine atom.
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.
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 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.
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 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.

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.
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.

Why the electron affinity is important?
Electron affinity for an atom is important to make it as a molecule.where atom is a small single one and molecule is the combination of two or more atoms.electron affinity is just a desire for attraction of electron by the atom.for example : We should have some affection for others to become their close relation like friends and live together in the same way a single atom should have desire [that is framed as ELECTRON AFFINITY] for electrons to be attached to form molecule
What is the difference between electron negativity and electrons affinity?
ok, so electron affinity is the amount of energy given off when a particular atom excepts electrons. Essentially, it is the likelihood that an atom will accept an electron, while ionization energy is how much energy is needed to take an electron off of a particular atom
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.
