Correct option is B
Melting point is a physical property of metals, as it relates to the change of state (from solid to liquid) without altering the chemical composition. Other physical properties include density, conductivity, and malleability.
Important Points:
· Reduction and oxidation are chemical properties.
· Corrosion is a chemical reaction between the metal and its environment.
· Metals generally have high melting points (e.g., tungsten has the highest melting point).
· Physical properties can be observed without changing the substance.
