Question

which of these is a property of a substance that is composed of atoms that are held together by metallic bonds?
it has a low melting point.
it can be flattened and bent.
it cannot be shaped into wires.
it does not conduct electricity.

Explanation:

Substances with metallic bonds are malleable (can be flattened) and ductile (can be bent or drawn into wires). They also have high melting - points and are good conductors of electricity. So the property of being able to be flattened and bent is correct.

Answer:

It can be flattened and bent.
