Question

Which of the following does not corrode when exposed to the atmosphere- a)Iron b)Copper c)Gold d)Silver

Answer 1

Hey mate

Answer Gold as it has very low reactivity

Answer 2

Answer:

c) Gold

Explanation:

• Gold is very least reactive hence does not corrode at all.
• And Au is a highly stable element because of its electronic distribution , hence it doesn't react easily.
• because they are unaffected by oxygen and most acids, and are more stable than many of their compounds, such as oxides or sulfides.
• This lack of chemical reactivity led to gold being called noble metals.
• The correct answer is option c) Gold.
