What does EA mean in UNCLASSIFIED

Electron affinity (EA) is a term used to describe the energy needed for an atom to capture an additional electron in order to form a negatively charged ion. The energy can also be released when a negative ion loses an electron.

Electron affinity can measure how much extra energy is gained or lost when a chemical reaction occurs. For example, if a molecule has a high EA, it means that it can absorb more electrons during the reaction and thus will release more energy than if it had a low EA.

Yes, there is one key difference between electrostatic and covalent binding in relation to EA. In electrostatic binding, the change in EA depends on both the distance between atoms and their charges, whereas in covalent binding, the change in EA only depends on the charges of each atom involved.

Bond strength refers to how strong two atoms are connected by either electrostatic or covalent forces. Generally speaking, higher bond strength results in lower EA because less energy needs to be expended for breaking up existing bonds in order for new ones to form.

Yes, temperature can have an effect on electron affinity as higher temperatures generally result in lower affinities due to increased thermal motion of electrons which reduces their ability to interact more strongly with surrounding atoms or molecules.
