Answer 1

Answer:

Ionization energy is the energy required to remove an electron away from an atom, which can be written as IE. Electron affinity, on the other hand, is the energy released when an electron is added to the atom. On the periodic table, electron affinity usually decreases down a group, and increases across a period
