Silver is a beautiful silvery white metal with good ductility, and its electrical conductivity and thermal conductivity are the highest among all metals. Silver is often used to manufacture highly sensitive physical instruments and components, various automation devices, rockets, submarines, computers, nuclear devices and communication systems. A large number of contacts in all these devices are made of silver.

Silver is added in large quantities to gels and bandages. The antibacterial property of silver comes from silver ions. Because silver ions can form strong bonds with substances used by some microorganisms to breathe (such as some molecules containing oxygen, sulfur and nitrogen), these substances can not be used by microorganisms, which leads to suffocation and death of microorganisms.
