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

Electron affinity is the change in energy of an atom with a neutral charge when an electron is added to form an anion. A more negative electron affinity corresponds to a greater attraction for an electron. Electron affinity become less negative down a group and from left to right in the periodic table. The correct answer would be the large nonmetal atoms. Large nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.
