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
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.
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 ionizaton energy present example?
An example of ionization energy is the energy required to remove an electron from a neutral helium atom to form a helium ion. This process results in the ionization of the helium atom, as it loses an electron and becomes positively charged.
Is energy absorbed or released to form positive ions?
Energy is typically absorbed to form positive ions through ionization. This process involves removing an electron from a neutral atom or molecule to create a positively charged ion. The energy required to remove the electron is known as ionization energy.
What is the electron affinity of yttrium?
The electron affinity of yttrium is 29.6 kilojoules per mole. This is how much energy this element releases when added to a single neutral, gaseous molecule or atom to create a negative ion.

Is electron is a positive?
yes it is
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 ionization energy required to add an electron to a netural atom?
Ionization energy is an expression linked to extraction of an electron.
What is the relationship between the ionization energy of a mono anion such as Cl and the electron affinity of the neutral atom?
The ionization energy of a monoanion (e.g., Cl^-) is the energy required to remove an electron from the monoanion to form a neutral atom. The electron affinity of the neutral atom (e.g., Cl) is the energy released when an electron is added to form a negative ion (e.g., Cl^-). In general, the ionization energy and electron affinity are related as they both involve the interaction of electrons with atoms, but they are opposite processes in terms of energy change.
Why does reducing a molecule give that molecule greater potential energy?
Reducing a molecule involves adding electrons, which increases its negative charge and potential energy. This is because the electrons will experience greater repulsion due to increased electron-electron interactions, leading to higher potential energy.
Why is electronic energy negative?
The charge on an electron is negative (by International Convention) - so electron energy is too
