검증된 단계별 안내1
Understand that the atomic number of an element is the number of protons in the nucleus of an atom of that element.
Recall that the periodic table is arranged in order of increasing atomic number, so each element has a unique atomic number.
Identify the element silver (Ag) on the periodic table by its symbol 'Ag'.
Look up the atomic number associated with silver (Ag) on the periodic table.
Confirm that the atomic number of silver (Ag) is 47, which means it has 47 protons.
