Use this infоrmаtiоn tо аnswer the next two questions: This grаph shows nucleon mass versus atomic number. Image Description Graph of average nucleus mass (y-axis) versus the atomic mass number (x-axis). The graph starts off with an average nucleus mass of 1.008 and decreases to 1.001 with an atomic mass number of 5. The line goes back up to 1.0025 until the atomic mass number is 10 before it decreases to just below 0.999 at around an atomic mass number of 55 before gradually increasing to 0.999 at atomic mass number 100, 0.9995 at atomic mass number 150, 1 at atomic mass number 210, and 1.0005 at atomic mass number 250.
