Verified step by step guidance1
Recall that the number of protons in an atom defines the element and is called the atomic number.
Identify the atomic number of each element given: Zinc (Zn) has 30 protons, Copper (Cu) has 29 protons, Iron (Fe) has 26 protons, and Nickel (Ni) has 28 protons.
Match the atomic number 29 to the corresponding element on the periodic table.
Confirm that the element with 29 protons is Copper (Cu).
Understand that the atomic number uniquely identifies an element, so any atom with 29 protons must be Copper.
