Question

Quizplus · Accepted Answer

Ionization energy and electron affinity generally increase as one moves across a period from left to right due to the increasing nuclear charge, which attracts electrons more strongly. Both decrease as one moves down a group because the outer electrons are farther from the nucleus and are more easily removed or added.
