LRA 211 Latest Update with Verified Solutions The three fundamental particles of the atom are the proton, neutron, electron The atomic nucleus contains protons and neutrons The component of the nucleus that has a positive charge and mass is the protons The component of the nucleus that has mass but no electrical charge is the Neutron If an atom has more electrons than protons, it will Negative When an atom becomes negatively or positively charged it is usually due to a change in the number ...

what mag modes are available? - correct answer if you have a 16" II, you can have 12,9,6, and 4.5 " Compton effect - correct answer hits the outer electron, incomplete transfer of energy, electron released and a low energy xray is deflected photoelectric absorption - correct answer x-ray totally absorbed by inner shell electron, x-ray overcomes binding energy and knock out the electron and an outer shell electron takes it place. When the outer electron moves to its new place, a charac...
