It is also referred to as the electron affinity rule.

Li also has the largest electron affinity in this group.

Electron affinity also shows a slight trend across a period.

In such a case, the atom's electron affinity value is positive.

As one progresses from left to right across a period, the electron affinity will increase.

In this case, the atom with the more positive energy value has the higher electron affinity.

This is quite a different matter than electron affinity.

A trend of decreasing electron affinity going down groups would be expected.

Likewise electron affinity is a also a positive number.

In some circumstances, electron affinity may even become negative.

To use electron affinities properly, it is essential to keep track of sign.

Each semiconductor has different electron affinity and band gap values.

This is the same sign convention as is used for electron affinity.

Generally, nonmetals have more positive electron affinity values than metals.

Electron affinity can be defined in two equivalent ways.

A uniform decrease in electron affinity only applies to group 1 atoms.

Properties of a free atom include ionization energy and electron affinity.

Fluorine (F) has a higher electron affinity than oxygen and so on.

By the way, electron affinities are not always exothermic.

Because of their high ionization energy and almost zero electron affinity, they were not expected to be reactive.

It has the lowest electronegativity and electron affinity of all the chemical elements.

However, electron affinities have not been measured for all the elements and so this formula is of at best very limited utility.

These materials are known as negative electron affinity materials.

The one-electron reduction potential of a molecule can be used to obtain an electron affinity.

Electron affinity is a phrase used in chemistry.
