Why do only the outer electrons leave their orbit shells?  Only outer electrons leave their orbit shells because electrons farthest from the nucleus are more easily freed from their orbits due to a weaker electrostatic force. What is required to have a balanced (or stable) atom?  The number of electrons must equal the number of protons in order to have a balanced atom. List the capacity of each of the first four orbital shells of an atom.  Shell: #1 = 2 electrons; #2 = 8 electr...
