Which particle largely determines the chemical properties of an atom?

Explanation:
Chemical properties stem from electrons, especially the valence electrons that participate in bonding. The arrangement of these outer electrons determines how an atom reacts, what kinds of bonds it forms, and where it sits in the periodic table. The nucleus sets the element’s identity and mass, but the bonds and reactions arise from how electrons are shared, transferred, or rearranged with other atoms. Neutrons influence isotopic mass and stability, yet they don’t directly govern chemical behavior, and the nucleus as a whole doesn’t take part in bonding. So, the electrons largely determine the chemical properties.
