Answer the following question given this paragraph: 

Because of their freely moving electrons, metals are good conductors of electricity. Metals also can be shaped without breaking. They are ductile (can be shaped into wires) and malleable (can be shaped into thin sheets). Metals have these properties because of the nature of their metallic bonds.


Q: The nature of what gives metals the properties of being ductile and malleable?


A:
metallic bonds
