Solving the Properties of Iron Ions Fe2+ and Fe3+

[SOLVED] Iron ions

I am curious about the properties of iron ions fe2+ and fe3+. As they are accelerated in a mass spectrometer, which would travel faster and have the largest radius. I understand that they have lost electrons and have a marginal loss in mass, as well I understand that a positively charged ion will attempt to return to a neutral state. However how do I prove it with the following:

m= qBr/2V, understanding that both B and r are squared.

Any help would be great, thanks.

Mass spectrometer strictly speaking measure mass/charge ratios - so an Fe2+ ion would behave the same as a Al+ ion with half the mass.
You generally try not to multiply ionize atoms to avoid this!
