Answer

Brief Explanations:

In isotopic notation $\ce{_{Z}^{A}E}$, by convention, the sub - script $Z$ represents the atomic number (number of protons) and the superscript $A$ represents the mass number (sum of protons and neutrons).

Answer:

$Z$ represents the atomic number. $A$ represents the mass number.
