Which of the following isotopes would deflect the most in a mass spectrometer? a) Sr-84
b) Sr-86
c) Sr-87
d) Sr-88

The correct answer is Sr-84. The lightest specie is the most deflected while the heaviest specie is the least deflected.

In mass spectroscopy, chemical substances can be identified by looking at their respective mass-to-charge ratios of gaseous ions in electric and magnetic fields. The is achieved using a mass spectrometer.

The lightest specie undergoes the greatest deflection while the heaviest specie undergoes the heaviest deflection accordingly in a mass spectrometer.

In this case, Sr-84, is the lightest specie hence it should be the least deflected specie.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
