Verified step by step guidance1
Recall that the identity of an element is determined by the number of protons in its nucleus, which is called the atomic number.
Look up the atomic number for each element given in the options: Iron (Fe), Cobalt (Co), Nickel (Ni), and Copper (Cu).
Match the atomic number 26 to the corresponding element. The atomic number 26 corresponds to Iron (Fe).
Understand that ions are atoms that have gained or lost electrons, but the number of protons remains the same, so the element identity does not change.
Therefore, an ion with 26 protons originates from the element Iron (Fe).
