Why do only the outer electrons leave their orbit shells? Answer 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? Answer 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. Answer Shell: #1 = 2 electrons; #2 = 8 ...
