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.
