Guida verificata passo dopo passo1
Recall that the number of protons in the nucleus of an atom defines the atomic number of the element.
Identify the atomic number given in the problem, which is 32 protons.
Use the periodic table to find the element with atomic number 32.
Locate the element with atomic number 32, which corresponds to Germanium (Ge).
Confirm that Germanium has 32 protons, distinguishing it from Zinc (30), Selenium (34), and Gallium (31).
