Question: Q: Why does metal conduct heat and electricity so well? Read this paragraph and choose the correct option from the provided answers: The metallic bonding model explains the physical properties of metals. Metals conduct electricity and heat very well because of their free-flowing electrons. As electrons enter one end of a piece of metal, an equal number of electrons flow outward from the other end. When light is shone on to the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light. This process is responsible for the high luster of metals. Choices: - electromagnetism - free flowing photons - insulation - free flowing electrons A:
Answer: free flowing electrons
