Guida verificata passo dopo passo1
Understand that the atomic number of an element represents the number of protons in the nucleus of an atom of that element.
Recall or refer to the periodic table to find the element with atomic number 47.
Locate the element with atomic number 47, which is positioned in the transition metals section of the periodic table.
Identify the symbol of the element with atomic number 47, which is Ag.
Confirm that Ag corresponds to silver, and verify that the other options (Pt, Pb, Au) have different atomic numbers.
