How Many Protons? The atomic number on the Periodic Table identifies the number of protons in any atom of that element. Copper, atomic number 29, has 29 protons. Finding the atomic number of an element reveals the number of protons.
ONE ATOM SAYS TO ANOTHER: 'OH NO, I'VE lost an electron'. The other replies: 'Are you positive?' This classic science classroom joke explains how cations form. Neutral atoms have the same number of positively charged protons in their nucleus as negatively charged electrons in their shells....
How many electrons are there in 1C? Charge: An atom is made up of electrons, protons, and neutrons. The positively charged nucleus is made of protons and neutrons whereas electrons revolve around the nucleus. The protons are positively charged and the electrons have an equal amount of negative...
