... An atom has a nucleus that holds protons and neutrons. Electrons orbit the nucleus. Protons have a positive charge and electrons have a negative charge, and just like a magnet, these opposite charges attract. That is, protons attract electrons. The negative electrons are attracted to the atom’s nucl ...
