The element fluorine's outermost energy level can hold eight electrons. Study the diagram of fluorine, and then determine if the following statement is true or false. If true, choose TRUE. If false, choose the rewording that is true. Fluorine's outermost energy level is filled, so fluorine is in its most stable state. A fluorine atom showing the electrons in each energy level. The first level has 2 electrons, and the second has 7.
