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.

Answer : The correct option is, It can be flattened and bent.

Explanation :

Metallic bond : It is defined as the bond that occurs in metals in which a metal consists of positive ions surrounded by the mobile electrons.

The characteristics of metallic bond are :

They are good conductors of heat and electricity.

They are lustrous.

They are malleable that means it can be flattened.

They are ductile that means it can be deformed into wires.

They have great strength.

Hence from the given options the correct option is, It can be flattened and bent.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
