Question

Which of the following does not corrode when exposed to the atmosphere-
1 point
iron
Gold
Copper
Aluminium

Answer 1

aluminium does not corrode when exposed to the atmosphere

Answer 2

Answer:

Gold does not corrode when exposed to the atmosphere.

Explanation:

Iron:

• It corrodes most because iron's electron easily binds with atmospheric oxygen.
• So, iron rusts or corrodes easily when exposed to the atmosphere.

Gold:

• Gold is a chemically inert compound and doesn't react with atmospheric oxygen.
• So, gold does not corrode when exposed to the atmosphere.

Copper:

• Materials made from copper easily corrode and lose its shine when exposed to water and other atmospheric factors.

Aluminium:

• Aluminium is highly reactive compound so comparatively it also gets corrode easily.
• When it's exposed to high pH the aluminium oxide layer will break and corrodes even more rapidly.

So, the correct answer is Gold which doesn't corrode when exposed to the atmosphere.
