Thomson decided to find out for sure. Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric and magnetic fields.
WebThomson made this discovery when his research student Francis Aston fired ionized neon through a magnetic and electric field – i.e. he used a mass spectrometer – and observed two distinct deflections. Thomson concluded that neon exists in two forms whose masses are different – i.e. isotopes. Web2 de fev. de 2024 · J.J.
