Step 1: Define Atomic number.
The atomic number ($Z$) is the number of protons in the nucleus of an atom. It uniquely identifies a chemical element.
Step 2: Define Isotope.
Isotopes are atoms of the same element (meaning they have the same atomic number or number of protons) but have different numbers of neutrons, resulting in different mass numbers.
Step 3: Explain why $^{12}\text{C}$ and $^{13}\text{N}$ are not isotopes.
$^{12}\text{C}$ has an atomic number of 6 (6 protons), making it carbon. $^{13}\text{N}$ has an atomic number of 7 (7 protons), making it nitrogen. Since isotopes must be atoms of
