The term that best describes the reaction of metals when exposed to corrosive factors is "corrosive reaction." This term directly relates to the process where metals deteriorate due to chemical interactions with their environment, such as moisture, acids, or salts. Corrosion often leads to the gradual degradation of the material, which can significantly compromise the metal's structural integrity.

While "chemical reaction" may seem relevant, it is a broader term that does not specifically indicate corrosion. Chemical reactions can encompass various types of processes involving different materials, not limited to corrosion.

"Electrical reaction" generally refers to processes involving transfer of electrons and ion movement, which may occur in specific electrochemical cells but does not capture the essence of the corrosion phenomenon observed in metals.

"Physical reaction" pertains to changes in state or appearance without altering the chemical composition of a substance, which is not applicable to the process of corrosion. Therefore, the specificity of "corrosive reaction" makes it the most accurate term to describe what happens to metals under corrosive conditions.
