J.J. Thomson was able to measure the charge to mass ratio of an electron. To do this he had to remove electrons from their parent atoms. He did this by Select one: a. Heating a metal filament in a vacuum, which created a cloud of electrons near the filament, then pulling the electrons away from the filament using a positive voltage. b. Bombarding a metal filament with alpha particles from a radioactive source. Oc. Bending a beam of electrons using an electric field. Od Using a combination of electric and magnetic fields.

The objective of this homework assignment is to expand your knowledge of the atom beyond the models presented in General Chemistry 1. To do this you will need to do a little research. Your task is to learn more about the CERN Large Hardon Collider and the research into sub-atomic particles. With that information, you need to teach one of your assigned classmates about one aspect of this research that you find more fascinating. Maybe you are intrigued about the production of man-made elements, or maybe you are intrigued about sub-atomic particles like quarks and the Higgs boson. Take your pick! Can someone please help!!
