Verified step by step guidance1
Identify the element symbol given in the problem, which is Zn (Zinc).
Recall that the number of protons in an atom is equal to the atomic number of the element.
Look up the atomic number of Zinc (Zn) on the periodic table; the atomic number is the number of protons.
Note that the atomic number of Zinc is 30, meaning it has 30 protons in its nucleus.
Therefore, the number of protons in an atom of Zn is 30.
