The statement that correctly summarizes the trend in electron affinity is the second option: it tends to be more negative across a period".<span> Electron affinity is the energy absorbed or released by a neutral atom when it absorbs an electron. The more negative the electron affinity the higher the affinity of the atom for an additional electron. So as the electronegativity trends to increase across a period, indicating that the atoms of the left side pull stronger the electrons, the fact that the electron affinity is more negative across a period tells that the atoms to the left accept better an additional electron.</span>
