verb; derivation
In Chemistry, the action of attaching an electron to an atom that requires a certain amount of energy called the electron affinity. This word is a neologism derived from electron affinity, the name of the measurement it relates to. My chemistry professor coined the word in lecture when she needed a way to describe the step in a Born-Haber cycle example where it is necessary to apply the numerical value of electron affinity to solve the problem. The word was formed by starting with electron affinity, clipping electron, then derived by adding the verb forming suffix –ize.
The next step in the cycle is to affinitize the chlorine atom.
Etymology : From Fr. affinite, from L affinitatem 'related or a relation by marriage' L ad + fin
