An electron accelerates through a twelve.five V potential contrast, starting from rest, and then crash with a hydrogen atom, exciting the atom to the highest energy level grant. List all the probable quantum-jump progression by which the excited atom could emit a photon and the wavelength of each.
O two gained
Fe three lost
Br one gained
Ni two lost
K one lost

-=gained as electrons have a negative charge
+=lost electrons
