Terms may be used more than once. noble gases transition elements alkaline-earth metals halogens alkali metal have a single electron in the highest energy level. a. The O~,L~(~L.~ f~J~L~ b. The~-~ ~-~h~L~.achieve the electron configurations of noble gases by losing two electrons. C. The ~_(~(,}~h~- __.L ~ vary in the number of electrons in the highest ener&~/level therefore they often have different oxidation numbers. have full sand p orbitals in the highest occupied energy levels. achieve the electron configurations of noble gases by gaining one electron. are stable and unreactive. achieve noble gas configuration by losing one electron.
