Question

An ore having two different metal atoms is

• A. Hematite
• B. Galena
• C. Magnetite
• D. Copper pyrite

Hint:

Magnetite is an ore of iron that contains both Fe²⁺ and Fe³⁺, making it an example of an ore with two different metal atoms.

Answer 1

The Correct Option is C

Step 1: Understanding the ore composition.
Magnetite (Fe₃O₄) is an iron ore that contains both iron (Fe) and iron (Fe²⁺ and Fe³⁺), meaning it has two different metal atoms. Step 2: Analysis of options.
(A) Hematite: Hematite is a mineral composed only of iron (Fe₂O₃) and does not contain two different metal atoms.
(B) Galena: Galena is lead sulfide (PbS) and contains only lead (Pb), not two different metal atoms.
(C) Magnetite: Correct — Magnetite is an ore that contains two different metal atoms (Fe²⁺ and Fe³⁺).
(D) Copper pyrite: Copper pyrite is copper iron sulfide (CuFeS₂) and contains copper and iron, but it only contains one metal atom in each ion.
Step 3: Conclusion.
The correct answer is (C) because magnetite contains two different metal atoms.
