Part a the emission line used for zinc determinations in atomic emission spectroscopy is 214 nm. if there are 1.00Γ1010 atoms of zinc emitting light in the instrument flame at any given instant, what energy (in joules) must the flame continuously supply to achieve this level of emission? express your answer numerically in joules.
part b during an emission, electrons move from a higher energy orbital to a lower energy orbital. which of the following are valid transitions that produce lines in the emission spectrum of zn?
check all that apply.
