Silver has a higher atomic number than copper.
The atomic number of an element corresponds to the number of protons in the nucleus of its atoms. Copper has an atomic number of 29, indicating that each copper atom contains 29 protons. On the other hand, silver has an atomic number of 47, meaning that each silver atom contains 47 protons.
In the periodic table, elements are arranged in order of increasing atomic number. Therefore, since the atomic number of silver (47) is greater than the atomic number of copper (29), silver has a higher atomic number than copper.
