a. What is the atomic symbol of holmium? b. How many protons and neutrons does an atom of holmium-151 have? c. Holmium-151 is a radioisotope that decays by emitting either a positron or an alpha particle. Write a balanced nuclear equation for the loss of a positron from holmium-151. d. Write a balanced nuclear equation for the loss of an alpha particle from holmium-151. e. Holmium-151 is formed from a particular radioisotope when it emits a positron. Write a balanced equation for this nuclear reaction. f. Holmium-151 is formed from a particular radioisotope when it emits an alpha particle. Write a balanced equation for this nuclear reaction. g. Holmium-151 has a half-life of 36 seconds. What percent of an initial sample of holmium-151 will remain after 360 seconds have passed?
