Periodic Trends in Relative Electron Affinity Part B Electron affinity, EA, is the energy required to add an electron to a neutral gaseous atom and is related to an element's position on the periodic table. Electron affinities can be positive, negative, or zero, as shown in the table. Electron affinity Element (kJ/mol) N (nitrogen) >0 Br (bromine) -325 Sr (strontium) -5 Rank the following elements by electron affinity, from most positive to most negative EA value. Rank from most positive...
