What is the key factor in determining the strength and hardness of an alloy?
The presence of only one type of metal atom.
The different sized atoms disrupting the metal structure.
The amount of carbon present.
The purity of the metal atoms.
Explanation
The disruption of the metal structure due to different-sized atoms is a key reason for the strength of alloys.
