Recall that the number of protons in an atom is called the atomic number, which uniquely identifies each element on the periodic table.
Look up the atomic numbers of the given elements: Iron (Fe), Nickel (Ni), Magnesium (Mg), and Manganese (Mn).
Identify the atomic number for each element: Iron has 26 protons, Nickel has 28 protons, Magnesium has 12 protons, and Manganese has 25 protons.
Compare the atomic numbers to find which element has exactly 25 protons.
Conclude that the element with 25 protons is Manganese (Mn), since its atomic number is 25.
