Answer
It can be flattened and bent.
Explanation
The question pertains to the properties of substances with metallic bonds. Metallic bonds are a type of chemical bond found in metal elements, where electrons are shared among a lattice of atoms. This type of bonding imparts several characteristic properties to metals:1. **High Melting Point**: Metals typically have high melting points due to the strong bond between the metal atoms and the sea of delocalized electrons. This contradicts the option stating "It has a low melting point."2. **Malleability and Ductility**: Metals are malleable (can be flattened) and ductile (can be drawn into wires). This is due to the ability of the atoms to slide over each other while maintaining the metallic bond. This aligns with the option "It can be flattened and bent."3. **Conductivity**: Metals are good conductors of electricity. This is because the delocalized electrons in the metallic bond can move freely, carrying electric current. This contradicts the option "It does not conduct electricity."Considering these properties, the option that correctly describes a property of substances with metallic bonds is the ability to be flattened and bent, reflecting their malleability and ductility.
