What is the approximate ratio of the mass of each positively charged particle in your lithium sample to each negatively charged particle in your lithium sample? O About 3:1 O About 14000:1 O About 7:1 O About 1000:1 O About 1.0e19:1 O About 1:1Calcium-48 is used to produce heavy elements. A research facility uses a particle accelerator that can accelerate a proton to 50 MeV to fire a beam of calcium ions at a target. The ion source uses an electric field to strip the valence electrons from the calcium atoms. What charge does this leave the calcium ions with? How much kinetic energy does each ion get from the accelerator? What is the velocity of the ions in the beam? What is the heaviest stable isotope that the ions in the beam could fuse with?
