Significant emission of Pt to the vapor phase was obsd. in a Pt/SiO2 model catalyst that was aged in flowing air at 800 °C. Adding Pd lowered the rate of emission, and so did decreasing the oxygen concn. WebThomson’s First Cathode Ray Experiment. Thomson had an inkling that the ‘rays’ emitted from the electron gun were inseparable from the latent charge, and decided to try and prove this by using a magnetic field. His first experiment was to build a cathode ray tube with a metal cylinder on the end. This cylinder had two slits in it, leading ...
WebMost relevant to the field of chemistry, Thomson found that the mass-to-charge ratio of cathode rays is independent of the nature of the metal electrodes or the gas, which suggested that electrons were fundamental components of all atoms.
