Some uses of:

Boron:
Borax, the most common natural form of boron, has a wide variety of uses. Borax is used in cleaning compounds, glass and ceramics, fertilizers, papers and paints, and fire retardants. Borax is also used in enamels covering the steel of refrigerators, washing machines, and other like objects.
Boron is almost as hard as diamond, so it is used in place diamonds in many cases.

Fluorine:
Most fluorine is used to make fluorine compounds. Fluorides are one form of fluorine compounds; they're fluorine with a metal. The most familiar use of a fluoride is in toothpaste. Fluorides are shown to help reduce tooth decay. The fluorides are added just as new tooth material is formed, making it strong and resistant to decay. Fluorides can also be added to a water supply to help prevent tooth decay. This process is called fluoridation and benefits mostly the younger citizens because their teeth are still developing.

Helium:

Some other common uses for helium include:

  • leak detection systems

  • welding

  • growing silicon and germanium crystals; protective shield

  • titanium and zirconium production; protective shield

  • nuclear reactors; cooling medium

  • diving and others working under pressure; artificial atmosphere with 20% oxygen

  • supersonic wind tunnels

  • cryogenic applications

  • liquid fuel rockets; pressurizing

Lithium
Lithium compounds are used in ceramics and glass, in primary aluminum production, in the manufacture of lubricants and greases, rocket propellants, vitamin A synthesis, silver solders, underwater buoyancy devices, batteries

Beryllium:
  • Turbine rotor blades
  • Laser tubes
  • Rocket engine liners
  • Springs
  • Aircraft brakes and landing gear
  • Ball bearings
  • Injection and blow mold tooling
  • Electrical contacts
  • Automotive electronics
Sulfur:
Use as Hardening agent in the manufacture of rubber products, such as tires.

Argon:

  • Argon fills incandescent light bulbs. This gas replaces the oxygen-rich air that corrodes the Tungsten filament and causes blackening of the bulb.
  • Argon provides the atmosphere for growing crystals to be used in the semiconductor industry, such as Silicon and Germanium.

Krypton:
Krypton is thus used in some types of photographic flashes used in high speed photography.

Xenon:
most common use is in lasers, also used in flash lamps, radioactive isotopes used in medical imaging.

Radon:
Radiation therapy and use in spas for curing arthriris.
