use of hydrogen
Hydrogen is the lightest element and can be used as a lifting agent in balloons. Since Hydrogen gas is highly flammable, it can be dangerous to use. But this property and others make Hydrogen suitable for use as a fuel. The most common use of Hydrogen is in chemical processes and reactions. -
use of hellium

widely used as an inert gas shield for arc welding in countries where helium is cheaper than argon
protective gas in growing silicon and germanium crystals, and in titanium and zirconium production
cooling medium for nuclear reactors
a mixture of 80% helium and 20% oxygen is used as an artificial atmosphere for divers and others working under pressure
cryogenic applications
as a gas for supersonic wind tunnels
a protective gas for -
use of lithium
Lithium is used for mental illnesses, including bipolar disorder, depression, and schizophrenia; for eating disorders, including anorexia and bulimia; and for blood disorders, including anemia and low white-cell count (neutropenia). -
use of beryllium
Beryllium is used in the manufacture of telecommunications infrastructure equipment, computers and cellular phones, thereby helping people around the world to keep in touch. -
use of carbon
Carbon is unique among the elements in the vast member and variety of compounds it can form. With hydrogen, oxygen, nitrogen and other elements it forms very large numbers of compounds, carbon atom often being linked to another carbon atom. This ability to form chains is unique to carbon, and it is thought to be an important reason for the dependence of life. It is also an indispensable source of such varied everyday products as Nylon and petrol, perfume and plastics, shoe polish, DDT and TNT. -
uses of oxygen
Oxygen is very reactive and capable of combining with most other elements. It is a component of thousands of organic compounds, and is essential for the respiration of all plants and animals and for almost all combustion. Indeed it is the most common element in the Earth’s crust. -
use of boron
boron is used in pyrotechnic flares to provide a distinctive green colour, and in rockets as an igniter. The most important compounds of boron are boric (or boracic) acid, widely used as a mild antiseptic, and borax which serves as a cleansing flux in welding and as a water softener in washing powders. compounds are also extensively used in the manufacture of borosilicate glasses. Pyrex glass is tough and heat resistant because of the boric acid used to make it. The isotope boron 10 is use -
use of nitrogen
Nitrogen is used as a refrigerant both for the immersion freezing of food products and for the transportation of food. Liquid nitrogen is also used in missile work and by the oil industry to build up great pressures in wells to force crude oil upwards. -
use of flourine
There was no commercial production of fluorine until World War II, when the production of the atom bomb and other nuclear energy projects made it necessary to produce large quantities. Fluorine is used to make uranium hexafluoride, needed by the nuclear power industry, and sulfur hexafluoride insulating gas for high-power electricity transformers, and to treat Polythene to make it impermeable to solvents. The element and its compounds are used in producing uranium and many fluorochemicals. -
use of neon
used in making neon advertising signs, which accounts for its largest use -
use of magnesium
used in flares and pyrotechnics, including incendiary bombs. It was used in flash photography, -
use of aluminum
Ancient Greeks and Romans used alum as an astringent, for medicinal purposes, and as a mordant in dyeing. It is used in kitchen utensils, exterior decorations, and thousands of industrial applications. -
use of phosphorus
used in the manufacture of safety matches, pyrotechnics, incendiary shells, smoke bombs, tracer bullets, etc. -
use of chlorine
production of safe drinking water the world over. Even the smallest water supplies are now usually chlorinated -
uses of argon
used in electric light bulbs and in fluorescent tubes at a pressure of about 3 mm, photo tubes, glow tubes, etc. -
use of potassium
the alloy of potassium with sodium (NaK) is used as a heat-transfer medium in nuclear reactors. The alloy is liquid at ambient temperature and is a good reducing agent in the chemistry laboratory -
use of calcium
Calcium is essential for human nutrition. Animals skeletons get their rigidity primarily from calcium phosphate. -
use of scandium
Scandium is used to make high intensity lamps. Scandium iodide is added to mercury vapor lamps to produce a light source with a color resembling sunlight. -
use of titanium
Titanium metal is used for alloys with with aluminium, molybdenum, manganese, iron, and other metals -
use of vanadium
Vanadium is used in nuclear applications, for producing rust-resistant spring and high-speed tool steels, and as a carbide stabilizer in making steels. Approximately 80% of the vanadium that is produced is used as a steel additive or ferrovanadium. -
use of chromium
used to harden steel, to manufacture stainless steel, and to form alloys -
use of manganese
Manganese is an important alloying agent. It is added to improve the strength, toughness, stiffness, hardness, wear resistance, and hardenability of steels. -
use of cobalt
alloyed with iron, nickel and other metals to make Alnico, an alloy of unusual magnetic strength with many important uses (jet engines and gas turbine engines) -
use of nickel
Nickel is used primarily for the alloys it forms. It is used for making stainless steel and many other corrosion resistant alloys. -
use of copper
Copper is widely used in the electrical industry. In addition to many other uses, copper is used in plumbing and for cookware. -
use of zinc
Zinc is used to form numerous alloys, including brass, bronze, nickel silver, soft solder, Geman silver, spring brass, and aluminum solder. -
use of gallium
Since it is a liquid near room temperature, gallium is used for high-temperature thermometers. -
use of germanium
Germanium is an important semiconductor material. It is commonly doped with arsenic or gallium at the level of one part per 1010 for electronics. -
use of arsenic
Arsenic is used as a doping agent in solid-state devices. Gallium arsenide is used in lasers which convert electricity into coherent light. -
use of selenium
Selenium is used in xerography to copy documents and in photographic toner. It is used in the glass industry to make ruby-red colored glasses and enamels and to decolorize glass. -
use of bromine
Selenium is used in xerography to copy documents and in photographic toner. It is used in the glass industry to make ruby-red colored glasses and enamels and to decolorize glass. -
use of krypton
used with argon as a low-pressure filling gas for fluorescent lights -
use of sodium
sodium metal is used in the preparation of tetraethyl lead, PbEt4, an important anti-knock reagent in leaded petrol (gasoline) - fortunately being phased out in many countries because of lead pollution problems -
use of silicon
doped with boron, gallium, phosphorus, or arsenic, etc. to produce silicon for use in transistors, solar cells, rectifiers, and other electronic solid-state devices -
use of sulfur
Most of the sulphur produced is used to produce sulphuric acid, H2SO4, the most important manufactured chemical in the world. Sulphuric acid has many uses, including for the synthesis of fertilisers and polyamides. It is used in batteries ("battery acid"). -
