Cancer therapy with radioactive rhenium-188 shows promise in patients suffering from colorectal cancer. a. Write the symbol for rhenium-188 and determine the number of neutrons, protons, and electrons. b. The half-life of rhenium-188 is 17 hours. If it takes 30 minutes to bind the isotope to an antibodythat delivers the rhenium to the tumor, what percentage of the rhenium remains after binding tothe antibody?
