Homework Help: chemistry

Posted by janice on Sunday, January 25, 2009 at 10:04pm.

Alloys are harder and stronger than pure metals. I saw this sentence,

"Alloys make the metal harder by preventing the layers of atoms from sliding."

I think it is more correct to add the word "easily" at the end of the sentence since in an alloy, it is more difficult for the layers of atoms to slide over each other.

What do you think?
