3 Protons 4 Neutrons 3 Electrons
For zinc the atomic weight is 6539 so the mass number is closest to 65. What is the charge of an atom with 12 protons and 10 electrons. Finding Protons Neutrons And Electrons Through The Atomic Number And Neutrons By Mass Atomic Proton Neutron Electron Protons Neutrons This is an ion which has lost 3 electrons therefore the number of electrons becomes 10 while the number of protons remains 13. . Protons Neutrons And Electrons Practice Worksheet Answers Key. Well for a start if you got 3 protons 3 massive positively-charged nuclear particlesthen what element you got. We got 3 fundamental negatively-charged particles of. The atom with 3 protons is atomic number 3 Lithium. The mass number is the number of protons plus neutrons therefore 28 14 protons equal 14 neutrons. In a neutral species the number of protons equals the number of electrons so silicon also has 14 electrons. An atom with 3 protons and 4 neutr...
