Chemistry Questions: Nuclear Reactions

Nuclear Reactions Matching; Pick from the following; Atomic number, Mass Number, Isotope, Radioactivity, LaBonte a. Latest student of the month b. Spontaneous decay of nucleus c. Sum of protons and neutrons d. Same atomic number, different mass number e. Number of protons in Nucleus (ID of atom) Matching radiation type: 42He+2 °oY i1e on Write the symbol on the line Positron Alpha Beta Gamma Neutron Balancing Nuclear equations, make sure the mass numbers (top) and atomic numbers (bottom) balance. Use periodic table to select element symbol! A fusion is joining of nuclei, fission is splitting of nuclei, radioactive emission is nuclei spitting out particles! Fusion in Sun 3HH + 1H *2He + Uranium alpha emission 23582U 42He + Thorium positron emission 23180Th °1e + - Actinium beta emission 23189 Ac + Splitting of Thorium nucleus by neutron bombardment. 23190Th + 'on 26Fe + A "chain reaction" is a "self sustaining" nuclear reaction. For instance in the neutron bombardment of 235u three high energy neutrons are produced which can hit three more Uranium nuclei producing nine more neutrons to continue the chain. What would cause the chain to stop? 235 92U + 1 on 3'n +
