What term describes the process by which metal is attacked and broken down by reactions with its environment (such as water)?

• A. Corrosion
• B. Oxidation
• C. Reduction
• D. Electron shell

Answer: (A)

Corrosion describes the gradual attack and breakdown of a metal caused by reactions with its environment, such as water. In many cases, corrosion involves oxidation, where metal atoms lose electrons and form ions that then combine with oxygen or water to create oxides or hydroxides. Oxidation is a key step, but the term corrosion captures the entire deterioration process. Reduction is the gain of electrons, which is the opposite, and the electron shell refers to the atomic structure, not a process of environmental attack. For example, iron rusting in wet conditions is a classic case of corrosion driven by electrochemical oxidation.
