Answer: Option (b) is the correct answer.
Explanation:
Chemical property is defined as the property which tends to bring change in chemical composition of a substance.
For example, reactivity, combustibility, flammability, etc are all chemical properties.
And, valence electrons are the electrons present in the outermost shell of an atom. The ability of an element to lend or borrow electrons helps to determine the reactivity of an element.
Thus, we can conclude that valence electrons determine an atom’s chemical properties.
