Final answer:
The properties of metals depend on the number and arrangement of electrons, not neutrons. Metallic properties, such as conductivity and malleability, are related to the presence of free-flowing electrons in metals.
Step-by-step explanation:
The properties of metals depend mainly on the number and arrangement of electrons, not neutrons. The number of protons determines the element and its chemical properties, while the number of neutrons can vary to create isotopes of the same element. Metallic properties, such as conductivity and malleability, are related to the presence of free-flowing electrons in metals.
