Verified step by step guidance1
Identify the element in question, which is nickel (Ni).
Recall that the number of protons in an atom is equal to the atomic number of the element.
Look up the atomic number of nickel on the periodic table; this number is unique to each element and represents the number of protons.
Note that the atomic number of nickel is 28, meaning every atom of nickel contains 28 protons.
Therefore, the number of protons in a nickel atom is 28.
