Question

the most negative electron affinity is most likely associated with which type of atoms?
large nonmetal atoms
small nonmetal atoms
large metal atoms
small metal atoms

Explanation:

Electron - affinity is the energy change when an electron is added to a gaseous atom. Non - metals have a greater tendency to gain electrons compared to metals. Small non - metal atoms have a higher effective nuclear charge and less electron - electron repulsion when adding an electron, resulting in a more negative (more exothermic) electron affinity.

Answer:

small nonmetal atoms
