Answer: Option (d) is the correct answer.Explanation: Out of the given options, options (d) represents the chemical property of silicon, because it shows that the silicon reacts with the fluorine.A physical property is a property that can be observed without any change in the chemical composition of the substance or molecule.For example, the color, the shape, the density, molecular weight, etc are all physical properties.A chemical property is a property that can be observed by the change of the chemical composition of the substance or molecule.For example, reactivity, flammability, oxidation state, etc are all chemical properties.Options (a), (b) and (c) are all showing the physical properties of silicon. Only choice (d) shows the chemical property.Therefore, it is the correct answer.
