Procedure 1. Complete the graph below by placing the percentage of parent isotope remaining after each half-life in the boxes provided on the graph. Remember that the percentage is cut in half with each passing half-life. The first two have been done for you. Afterwards, answer the questions given below. a. What percentage of parent isotope is left after zero half-lives? b. What percentage of parent isotope is left after one half-life? c. What percentage of parent isotope is left after two half-lives? d. What percentage of parent isotope is left after three half-lives? e. What percentage of parent isotope is left after four half-lives? 1. What percentage of parent isotope is left after five half-lives? g. What percentage of parent isotope is left after six half-lives? h. What percentage of parent isotope is left after seven half-lives? i. What happens to the percentage of parent isotope as the number of half-lives increase?
