The chemical properties of an element are determined by its electronic configuration, specifically the number and arrangement of electrons in the outermost shell (valence shell). These valence electrons are involved in chemical bonding and reactions.
Statements A, B, and C relate to the nucleus and mass of the atom. The number of isotopes (A), mass number (B), and number of neutrons (C) affect the physical properties (like density, melting point, boiling point, radioactive decay) but generally do not significantly alter the chemical behavior of an element.
