Describe the behavior of the model electrons. 8. What do you get if the number of protons and electrons in your model is not equal 9. Fill out the chart for these elements: oxygen, neon, aluminum, iron, gold. Name Oxygen Neon Aluminum Iron Gold Symbol Protons Neutrons Electrons Weight (...
electrons than protons. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. If an ion has a 2+ ...
