Question

C) Several scientists believe that if they can calculate the half-life of the unknown sample, they may be one step closer to determining where the sample may be from. The line graph below demonstrates the concept of half-life. Using your knowledge of atoms and half-life, explain what exactly this graph shows. What do the x- and y-axes represent? Give an example of a known element and its half-life to help support your answer. (3 points)
