When does the electron shown release the greatest amount of energy as it moves from one level to another? g. s. to s.1.s.1. to g. s.s.1. to s.2.s.2. to s.1.

S1 to GS as the amount of energy required to remove the electron is greatest when it is closest to the nucleus. think about two magents. does it take more energy to spereate them when they are far apart or when they are very close together? it's the same idea with electrons. the more energy required to remove, the more energy will be emmitted.
