As we go across the period, electron affinity values  become more negative.

Electron affinity refers to the energy released when one mole of electrons is added to a gaseous atom to yield one mole of gaseous ions with a negative charge. This trend increases across a period but decreases down the group.

Hence, as we move across the period, more energy is released as electrons are added to atoms and electron affinity values become more negative.
