Guida verificata passo dopo passo1
Recall that the number of protons in the nucleus of an atom defines the atomic number of an element.
Identify the atomic number of each element given in the options: Cobalt, Germanium, Phosphorus, and Sulfur.
Use the periodic table to find the atomic number for each element: Cobalt (27), Germanium (32), Phosphorus (15), and Sulfur (16).
Compare the atomic numbers to the given number of protons (32) to find the matching element.
Conclude that the element with 32 protons is Germanium, since its atomic number is 32.
