Detailed explanation-1: -The chemical properties of an atom depend upon the atomic number. From the atomic number, we can get valence electrons that determines the chemical properties of it.

Detailed explanation-2: -The presence of valence electrons can determine the element’s chemical properties and whether it may bond with other elements: For a main group element, a valence electron can only be in the outermost electron shell.

Detailed explanation-3: -The chemical properties of an element are determined by the number of electrons in its atom, which in turn is determined by the number of protons.

Detailed explanation-4: -The presence of valence electrons can determine the element’s chemical properties, such as its valence-whether it may bond with other elements and, if so, how readily and with how many. In this way, a given element’s reactivity is highly dependent upon its electronic configuration.
