← A lithium ion with a single electron, Li²⁺, has a nucleus of charge 3e. Its electron falls from the level n = 5 to the level n = 3. Find the wavelength of the emitted photon, taking hc = 1240 eV nm.Some atoms of hydrogen gas sit in the fifth level. They can fall one level or several at a time. How many different photon wavelengths are possible? →
