WebSo to three significant figures, the charge-to-mass ratio of an electron is negative 1.76 times 10 to the 11th coulombs per kilogram. Note that this answer is negative because the charge of an electron is negative. Also, if we’d used different units, we would’ve gotten a very different numerical answer because, for example, in units of the ...

WebThe mass-to-charge ratio, is a physical quantity that is widely used in the electrodynamics of charged particles, e.g. in electron optics and ion optics. It appears in the scientific fields of lithography, electron microscopy, cathode ray tubes, accelerator physics, nuclear physics, auger spectroscopy, cosmology and mass spectrometry. WebIn the analytical technique of mass spectrometry, atoms or molecules are ionized using a high-energy electron beam and then separated based on their mass-to-charge ratios (m/z). The results are presented as a mass spectrum, which shows the relative abundances of the ions on the y-axis and their m/z ratios on the x-axis.
