behavior using classical physics is not possible due to quantum effects. More than 99.94% of an atom's mass is in the nucleus.[1] Protons have a positive electric charge and neutrons have no charge, so the nucleus is positively charged. The electrons are negatively charged, and this opposing charge is what binds them to the nucleus. Less
