What is Silver?

  • Silver is the most conducting metal with atomic number 47 and represented with the symbol ‘Ag’ in the periodic table.
  • Silver is abundant in mineral rich soils. It is available in the mixed form, generally in crystal form.
  • Plants absorb silver and measured levels in the soil come around 0.03 – 0.5 ppm.

Physical properties of Silver

  • Silver ( Ag ) is a white, soft, lustrous, very ductile and malleable metal.
  • It is a very good conductor of electricity and heat.
  • It has the highest electrical conductivity of all metals, but the high cost of it has restricted us from using it in all electrical devices.

Applications and Effects of Silver

  • The principle use of this metal is a precious metal, including jewelry and decorative items.
  • The other applications include:
    • Currency – still in some countries silver coins are used as currency.
    • Jewelry and silverware
    • It is used in manufacturing of solar panels
    • Air conditioning – It is used in manufacturing of typical air conditioners
    • Water purification – It is used in water purifiers to prevent the growth of algae and bacteria in filters
    • Photography and electronic devices
    • Used as an antibiotic coating in medical devices
    • Thermal or infrared coatings use silver as it reflects some wavelengths better than aluminum.
