What is the relationship between the atomic number of an element and its atomic radius from the graph of your lab report?

Atomic number = number of protons

Atomic Mass number = number of protons + number of neutrons

Relative mass number = the weighted average mass numbers of the naturally occurring isotopes as compared to C-12

If you delete the atomic number from the mass number you get the number of neutrons. The atomic number is the number of protons and electrons. (They are both the same number.)
