Review Questions

• How does the structure of copper contribute to its properties as a metallic solid?
  • Copper's face-centered cubic (FCC) structure allows for close packing of atoms, which enhances its ductility and malleability. This structure facilitates the movement of dislocations within the metal, making it easy to shape without breaking. Additionally, the arrangement of atoms enables efficient conduction of electricity and heat, making copper an ideal material for electrical wiring.
• Discuss the role of copper in biological systems and why it's considered essential for health.
  • Copper plays several critical roles in biological systems, including acting as a cofactor for enzymes involved in energy production and iron metabolism. It helps form red blood cells and maintains healthy bones, blood vessels, nerves, and immune function. The body's ability to utilize copper efficiently highlights its bioavailability, making it essential for overall health.
• Evaluate the significance of copper's antimicrobial properties in medical applications and public health.
  • The antimicrobial properties of copper are significant for both medical applications and public health because they help reduce the transmission of infections in healthcare settings. Copper surfaces can kill a wide range of pathogens on contact, which is crucial for preventing hospital-acquired infections. This quality also makes copper valuable in designing tools and surfaces that enhance hygiene and safety in various environments, ultimately improving patient outcomes and public health initiatives.
