Active recall

Quick check

Answer each question before opening the answer.

What is an alloy and why is it harder than the pure metal?

A mixture of a metal with other elements; the different-sized atoms distort the layers so they cannot slide easily.

Give an example of an alloy and what it contains.

Steel (iron + carbon) or brass (copper + zinc).
