Thomson determined which quantity for the electron?

1. Thomson's cathode ray tube deflected the beam in electric and magnetic fields. 2. That experiment cannot separate charge from mass on its own. 3. The charge-to-mass ratio was known due to Thomson's research, at 1.759 times ten to the eleventh coulombs per kilogram. 4. Millikan later supplied the charge, and combining the two gave the mass. 5. Nuclear binding energy belongs to a much later era of physics. _Source: OpenStax Chemistry 2e (CC BY 4.0), Ch 2 'Atoms, Molecules, and Ions', sections 2.1-2.6_
