Detailed Solution

The lowest ionisation energy is allegedly found in cesium. The ionisation energy drops from top to bottom within a group as a result of the shielding effect.
Compared to nonmetals, metals have a lower electron affinity. Nonmetals: To have an octet that is completely stable, nonmetals like to gain electrons and produce anions. The electron affinity of nonmetals is higher than that of metals because they release energy (exothermic) to acquire electrons in order to form an anion.
