Best Answer

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.

Fluorine has greater electron affinity than bromine, or any other element.

Which element has the highest electron affinity?

Chlorine has hig electron affinity while fluorine has high electro negativity

What is the halogen with the least negative electron affinity?

The halogen with the least negative electron affinity is Fluorine. Fluorine has the highest electron affinity of any element and is also the most electronegative.

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 Iodine have less electron affinity than fluorine?

Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine

Which has lower electron affinity between oxygen and fluorine?

This element is fluorine.

Do Nonmetals with lower electron affinity have higher reactivity?

No. The most reactive non metal, fluorine, has the highest electron affinity.

What elements has the largest electron affinity?

These elements are halogens.

Is oxygen has more electron affinity than sulfur?

Yes. Oxygen has greater electron affinity than any other element except fluorine.

Halogen with the least-negative electron affinity?

The halogen with the least-negative electron affinity is astatine. Electron affinity and electronegativities decreases down a group. Since astatine is the last halogen located in Group 17 as you move down the column from fluorine, it has the least negative electron affinity.

Why does chlorine have more electron affinity than fluorine although it is below fluorine in periodic table?

Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine.(Note that the most electronegative element is fluorine however; 'electronegativity' is not exactly the same as 'electron affinity'.)Electronegativity is the ability of an atom in a molecule to draw bonding electrons to itselfElectron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.The reason that the electron affinity is not as high as might otherwise be predicted for fluorine, is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).
