Doubly ionized lithium li2+ (z = 3) and triply ionized beryllium be3+ (z = 4) each emit a line spectrum. for a certain series of lines in the lithium spectrum, the shortest wavelength is 40.5 nm. for the same series of lines in the beryllium spectrum, what is the shortest wavelength?

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.
