Answer:
1.rocket fuel.
welding.
production of hydrochloric acid.
reduction of metallic ores.
2. Helium is used as an inert-gas atmosphere for welding metals such as aluminum; in rocket propulsion
3. Lithium is used to treat and prevent episodes of mania (frenzied, abnormally excited mood) in people with bipolar disorder (manic-depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods).
4. Beryllium is used in gears and cogs particularly in the aviation industry. Beryllium is a silvery-white metal. It is relatively soft and has a low density. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools.
5.boron is used as a rocket fuel igniter and in pyrotechnic flares.
6.Carbon (in the form of coal, which is mainly carbon) is used as a fuel. Graphite is used for pencil tips, high temperature crucibles, dry cells, electrodes and as a lubricant.
7.The chemical industry uses this gas in the production of fertilizers, nylon, nitric acid, dyes, medicines, and explosives.
8.Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.
9.Fluorine is critical for the production of nuclear material for nuclear power plants and for the insulation of electric towers.
10. Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant.
11. Sodium is used as a heat exchanger in some nuclear reactors, and as a reagent in the chemicals industry
12.Magnesium is used in products that benefit from being lightweight, such as car seats, luggage, laptops, cameras and power tools.
13. Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts.
14.is used to make concrete and brick; it is a useful refractory material for high-temperature work, and in the form of silicates it is used in making enamels, pottery, etc.
15.The main function of phosphorus is in the formation of bones and teeth.
16.It is used for making car batteries, fertilizer, oil refining, water processing, and mineral extraction
18.Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements
19.It helps your nerves to function and muscles to contract. It helps your heartbeat stay regular.
20. Calcium is also used in the production of some metals, as an allying agent. Calcium carbonate is used to make cement and mortar and also in the glass industry.
