Guida verificata passo dopo passo1
Recall that the number of protons in an atom is given by its atomic number, which is unique to each element.
Identify the element in question, which is zinc (Zn).
Look up the atomic number of zinc on the periodic table; this number represents the number of protons in a zinc atom.
Understand that the atomic mass (such as 65) is not the number of protons but the total number of protons and neutrons combined.
Conclude that the correct number of protons in a zinc atom corresponds to its atomic number, which is 30.
