Question
What is the main difference in composition between a pure metal and an alloy?
Answer
A pure metal consists of only one type of atom, while an alloy is a mixture of two or more different metals or a metal and another element. This difference in composition affects their properties and uses.
Explanation
This question tests the understanding of the basic definitions of pure metals and alloys, which is fundamental in materials science. It requires students to recall the definitions and apply them to distinguish between the two.
Common mistake
Confusing Pure Metals and Alloys
Students often think that a pure metal and an alloy have the same composition, not recognizing that alloys are mixtures of different elements.
To fix this, remember that a pure metal consists of only one type of atom, while an alloy contains two or more different elements combined together.
