Review Questions

• Explain how the position of silver in the electrochemical series affects its behavior in galvanic cells.
  • The position of silver in the electrochemical series, which ranks elements based on their reactivity, is towards the less reactive end. This means that silver has a relatively high reduction potential, making it a good cathode material in galvanic cells. When silver is paired with a more reactive metal, such as zinc or copper, the more reactive metal will preferentially undergo oxidation (become the anode), while silver will undergo reduction (become the cathode). This difference in reactivity is the driving force behind the generation of an electrical current in a galvanic cell.
• Describe how the periodic trends in atomic radius and ionization energy influence the properties and behavior of silver as a transition metal.
  • As a transition metal, silver exhibits periodic trends in its atomic radius and ionization energy that contribute to its unique properties. The atomic radius of silver is relatively small compared to the alkali and alkaline earth metals, due to the presence of partially filled d-orbitals. This compact atomic structure, along with the high nuclear charge, results in strong metallic bonding and high electrical and thermal conductivity. Additionally, silver has a high ionization energy, making it less reactive and more resistant to oxidation than more electropositive metals. These periodic trends in atomic radius and ionization energy help explain silver's stability, malleability, and widespread use in various applications, including electronics, jewelry, and catalysis.
• Analyze the role of silver in the occurrence, preparation, and properties of transition metal compounds, and how these factors contribute to its diverse applications.
  • Silver is an important transition metal that plays a significant role in the occurrence, preparation, and properties of transition metal compounds. Silver compounds, such as silver nitrate (AgNO$_3$) and silver chloride (AgCl), can be readily prepared through chemical reactions and are widely used in various industries. The unique properties of silver, including its high electrical and thermal conductivity, antimicrobial activity, and corrosion resistance, make silver-containing compounds valuable in applications ranging from photography and electronics to medical devices and water purification. Furthermore, the ability of silver to form stable complexes with organic and inorganic ligands allows for the synthesis of a diverse array of silver-based compounds with tailored properties, further expanding the versatility and applications of this transition metal.
