Question

Which one of the following elements in the Earth is a chalcophile and shows siderophilic behavior?

• A. Mg
• B. Fe
• C. Li
• D. Pb

Hint:

Siderophile elements like Fe are typically concentrated in the Earth's core due to their affinity for metallic iron.

Answer 1

The Correct Option is B

Step 1: Understanding Chalcopyrite and Siderophilic Behavior.
A chalcopyrite element tends to concentrate in metallic ores, particularly copper-based ores. A siderophile element, on the other hand, is one that has an affinity for iron and tends to be found in metallic iron.
Step 2: Analyzing the Options.
- Fe (Iron) is a siderophile element, meaning it has a strong affinity for metallic iron and is concentrated in Earth's core.
- Mg (Magnesium) and Li (Lithium) are not considered siderophile elements.
- Pb (Lead) is not a chalcopyrite or siderophile element.
Thus, the correct answer is (B) Fe.
Final Answer: \[ \boxed{\text{Fe}} \]
