thanks!!

antimony-126 p decay electron capture positron emission a decay phologre hic plate C. Identify the three types of radioactive emissions depicted in the diagram to the right. 3= Lead block Radioactive material till Voltage source D. Identify which of the following statements are true for chemical reactions (CR) and those for nuclear reactions (NR). 1. _One substance is converted into another, but the atoms never change identity. 2. Orbital electrons are involved as bonds break and form. 3. Atoms of one element typically converted into atoms of another element 4. Protons, neutrons and other particles are involved; orbital electrons rarely take part. 5. Reactions are accompanied by relatively small changes in energy and no measureable changes in mass. 6. Reaction rates are influenced by temperature, concentration, catalysts and the compound in which an element occurs. 7. Reactions are accompanied by large energy changes and measureable mass changes. 8. Reaction rates are affected by the number of nuclei, but not by temperature, catalysts or, normally, the compound in which the element occurs. Page 6 of 6
