A.n = 5 to n = 1
B.n = 3 to n = 2
C.n = 5 to n = 2
D.n = 1 to n = 3
E.n = 3 to n = 1

jfraser · Answer

if the electron ABSORBS a photon, that means it must GAIN energy. The only transition where energy is gained is from a low level to a higher level

jfraser · Answer

when electrons RELEASE photons, they drop in energy, which is why we see colors in an emission test. Read the question carefully
