Web12 okt. 2024 · Sodium has 11 protons 12 neutrons and 11 electrons. What are the rules for electron shells? electron shell rules. electrons always occupy shells or energy levels, lowest are always filled first, 1st shell has 2 electrons, 2nd shell has 8 electrons, 3rd shell has 8 electrons, atoms want full shells, most atoms aren’t full. ionic bonding. Web2 aug. 2024 · For all atoms with no charge, the number of electrons is equal to the number of protons. number of electrons = 30. The mass number, 65, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons = 65 − 30 = 35. Exercise 4.8.3. four square go green organic spa
