Electron affinity

Electron affinity

It is the amount of energy given out when an electron is added to a neutral gaseous atom. This results in the formation of an anion.

For example Cl + e– → Cl + energy. The electron affinity of chlorine is 348 kJ mol-1.

Electron affinity changes across a period. The electron affinity of the atoms increases from left to right along a period…

affinity chromatography

affinity chromatography A bio­chemical technique for purifying nat­ural polymers, especially proteins. It functions by attaching a specific lig­and by covalent bonding to an insolu­ble inert support. The ligand has to have a specific affinity for the poly­mer, so that when a solution contain­ing the ligand is passed down a column of the material it is specifi­cally retarded and thus separated from any contaminating molecules. An example of a…
