Excitation of the 3s electron from Mg+ to a 3p orbital occurs at 280.0 nm. The probability of filling a 3p orbital relative to the 3s orbital is 3/1. Assuming that the total Mg+ population in a given atomization source is 3.5 x 10^18 ions at any given time, what would be the number of ions that are in the excited 3p state for
A) an air/acetylene flame at 2100 C
B) an argon plasma at 8000 C
C) Which source (flame or plasma) would be best for detecting atomic emission from Mg+?
