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 electrons; #3 = 18 electrons; and #4 = 32 electrons. What is the maximum electron capacity of a valence shell? - A valence shell can hold a maximum of eight electrons. Electrons in orbits nearest the nucleus contain _________ energy than those in more distant orbits. - Electrons in orbits nearest the nucleus contain less energy than those in more distant orbits. What will happen to a valence electron that has enough energy added to it? - A valence electron that has enough energy added to it will move away from its atom. What major factor determines which category a particular element belongs? - The number of electrons in the valence shell determines the element category. How many valence electrons are there in a good conductor? - A good conductor has only one or two valence electrons. List gold, silver, and copper in the order of best conductivity. (List the best conductor first.) - #1 Silver; #2 Copper; #3 Gold
