Recall that the number of protons in an atom is equal to its atomic number, which uniquely identifies the element.
Identify the element in question, which is zinc in this problem.
Look up the atomic number of zinc on the periodic table; this number represents the number of protons in a zinc atom.
Understand that the atomic number is not the same as the atomic mass (which is approximately the sum of protons and neutrons).
Conclude that the number of protons in a zinc atom is equal to zinc's atomic number.
