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.

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 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.

If a neutral atoms gains electron what type of particle is formed?

An electron has a negative charge, so if a neutral atom gains an electron, it becomes a negative ion. A negative ion is called an anion.


How does a positive ion become a neutral atom?

A positive ion can become a neutral atom by gaining electrons. When a positive ion gains one or more electrons, it becomes neutral because the negative charge of the electron(s) cancels out the positive charge of the ion.


What happens when a electron moves to higher energy level?

The electron gains energy.


What is the first electron affinity of magnesium and is it exothermic or endothermic?

The first electron affinity of magnesium is exothermic. This means that energy is released when a neutral magnesium atom gains an electron to form a magnesium ion.


If a neutral atom loses or gains an electron what is formed?

An Ion. More specifically if it gains an electron it becomes an anion and it it loses an electron it becones an cation (pronounced Kat-ion)


Is oxygen neutral atom or ion?

A neutral atom, it only becomes an ion after it loses or gains an electron.


What happens when an electron moves to a higher level?

The electron gains energy.


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 mono-anion such as Cl- is the amount of energy required to remove an electron from the anion to form a neutral atom. Electron affinity is the energy released when an atom gains an electron to form an anion. They are related as the ionization energy of Cl- is equal in magnitude but opposite in sign to the electron affinity of the Cl atom.
