“Ability to form a compound” is a chemical property.
Answer: Option A
Explanation:
Each element exhibits its characteristic physical and chemical properties. The physical properties of an element describes the boiling point, melting point, freezing point, density, inherent state of matter, electrical and thermal conductivity, etc. The change in physical properties occur when there is a change in the phases and not any change in the chemical composition.
But for chemical properties, these properties explain the bond strength of the elements. It helps to decide the reactivity, flammability of substances. The chemical properties of substance or element decide how easily it can react or get burned.
Any properties or reactions which lead to formation of compounds different from the reactants are considered as chemical change of the reactants. So we can say that the ability to form a compound is a chemical property as in this case, the reactants will react with each other in presence of external heat if required to form the product compound whose chemical composition and properties will be different from the reactants.
