Web27 okt. 2015 · A few important aspects about the sign used to express electron affinities.. Electron affinity is directly related to change in energy by the equation #"E"."A". = -Delta"E"# This means that if energy is released when an atom is added to the atom, i.e. #Delta"E"# is negative, the electron affinity will be positive.. Likewise, if energy is … WebSee Answer. Question: Rank the following elements by electron affinity, from most positive to most negative EA value. Rank from most positive to most negative.
