Final answer:
The graphing assignment in nuclear physics involves comparing the number of neutrons to the number of protons. By analyzing the stability and characteristics of different nuclei, we can understand the relationship between N and Z. For a given Z, there can be multiple values of N, indicating the existence of isotopes.
Step-by-step explanation:
In the context of nuclear physics, the graphing assignment involves comparing the number of neutrons (N) to the number of protons (Z), also known as the atomic number. By plotting N vs Z on a graph, we can analyze the stability and characteristics of different nuclei. For a given value of Z, there can be multiple values of N, indicating the existence of isotopes with different neutron numbers for the same element.
