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.

B: it can be flattened and bent

Explanation:

Metals are malleable and can be flattened. Metals are ductile and can be deformed and bent.

Metals are bonded together by metallic bonds.

Hence a substance that is composed of atoms that are held together by metallic bonds can be flattened and bent.
