Question

Which of the following metals is generally found in free state?

• A. Cu
• B. Au
• C. Al
• D. Fe

Hint:

Noble metals like gold (Au) and platinum (Pt) are usually found in their free, elemental state in nature due to their low reactivity.

Answer 1

The Correct Option is B

Step 1: Understanding free state metals.
Metals found in their free state in nature are typically noble metals, which are less reactive. These metals do not easily form compounds and are found in their elemental form. Step 2: Analysis of options.
(A) Cu: Copper can be found in both free and combined states, but it is not as commonly found in the free state as gold.
(B) Au: Correct — Gold (Au) is a noble metal and is commonly found in its free, elemental state in nature.
(C) Al: Aluminum is highly reactive and is not found in its free state; it is usually found as a compound like aluminum oxide.
(D) Fe: Iron is typically found in combined states like iron ore, not in its free state.
Step 3: Conclusion.
The correct answer is (B) because gold (Au) is commonly found in its free state in nature.
