Alloys Defined as Mixtures Steps:

• Define alloy: homogeneous mixture of metals or metal with non-metal.
• Check A: alloys are mixtures, not compounds.
• Check B: matches mixtures including non-metals like carbon in steel.
• Check C and D: contradict bonding and property facts.

Why B is correct:

• Alloys form by mixing metals with non-metals (e.g., brass: copper-zinc; steel: iron-carbon), per metallurgical definition of homogeneous solid solutions.

Why the others are wrong:

• A: Alloys are mixtures, not chemical compounds with fixed ratios.
• C: Alloys conduct via delocalized electrons in metallic bonds, not ionic bonds.
• D: Alloys have modified properties (e.g., harder than pure metals) due to lattice distortion.

Final answer: B
