Hello, I Have Some Question , Is Hydrogene atom able to become a negative ion ? Why not ? Another question. We have a stable Hydrogene atom , how many possibilities can we get when moving the electron to to the 3rd orbit ? I Was thinking of unlimited possibilites , because we can can send the electron to any orbit and get see if it get back to the 3rd one ... My teacher says that there's two solutions , the first says 1 ( if the energy is EXACTELY enough for the electon to move there , he will move , otehr wise , nothing happens ) the second says , 3 ( 1 successful try , and 2 faulty ones ) Thanks In adcance .
