Which term denotes a metal property indicating resistance to oxidation when exposed to air?

• A. Oxidization resistance
• B. Mechanical properties
• C. Non-toxic
• D. Particle boards

Answer: (A)

The key idea here is how a metal reacts with oxygen in the air. Oxidation resistance describes how well a metal resists forming oxides when it’s exposed to oxygen, which is what happens on exposure to air. Metals with high oxidation resistance either form a protective oxide layer that slows further reaction or simply don’t react readily, helping them stay durable in air.

That’s why the term oxidation resistance is the best fit. The other options don’t fit the concept: mechanical properties relate to strength and how the material responds to forces; non-toxic refers to safety for people or the environment; particle boards describe a type of material, not a metal property.
