Answer 1

Explanation:

in this question, we're asked how to determine whether we have a metallic or nonmetallic substance.So what you want to do is one to remember that metals are malleable and Nonmetal are brittle. So if we were to hammer the metal, it would be very malleable, but the nonmetal would fall apart. And never we could just hammer the sample and see whether it was malleable. And therefore it would be a medal or a brittle and therefore being nonmetal.
