Air Force, facing fighter pilot shortage, offers retention bonuses of up to $225,000. The Air Force estimates that without a serious recruiting effort, it will be short 700 fighter pilots eight years from now -- so it is offering retention bonuses of up to $225,000 to stay in the service for an additional nine years. The deadline to respond to this unusual help wanted ad is Sept 30.
A community for students. Which energy transition may take place in the atom if its electron has absorbed a photon? A.n = 5 to n = 1 B.n = 3 to n = 2 C.n = 5 to n = 2 D.n = 1 to n = 3 E.n = 3 to n = 1 Help me!!! if the electron ABSORBS a photon, that means it must GAIN energy. when electrons RELEASE photons, they drop in energy, which is why we see colors in an emission test.
What is the wavelength of the photon emitted when a hydrogen atom goes from the second energy level to the first energy level? A hydrogen atom becomes ionized when its electrons have enough energy to jump out of the outermost energy level and become free of the atom. An electron near to escaping the atom has the most energy and therefore emits a high-energy photon if it drops all the way to level one. If the photon contains more energy, it has a higher frequency. Also, the lower energy levels are farther apart than the upper levels.
