NCTI Installer Tech 100% SOLUTIONS REVISED 2023//2024 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 or...
