Question

Trends in EA are not as clear as others but In general, nonmetals have more _________ electron affinity (EA) than metals.

A) Positive
B) Negative
C) Neutral
D) Variable

Answer 1

Nonmetals have more negative electron affinity (EA) than metals. Electron affinity is the energy change for the process of adding an electron to a gaseous atom to form a negative ion.

Step-by-step explanation:

In general, nonmetals have more negative electron affinity (EA) than metals. Electron affinity is the energy change for the process of adding an electron to a gaseous atom to form a negative ion. Nonmetals, such as chlorine, oxygen, and nitrogen, have a greater tendency to gain electrons and form anions, which results in a more negative electron affinity. Metals, on the other hand, tend to lose electrons and form cations, leading to a lower electron affinity.
