uses of noble gases
Solution
Noble gases, also known as inert gases, have several uses due to their unique properties. Here are some of their uses:
-
Helium (He): This gas is lighter than air, making it ideal for filling balloons and airships. It's also used in diving gas mixtures to prevent the bends, and in cryogenics for its low boiling point.
-
Neon (Ne): Neon is famous for its use in neon signs, where it glows a distinct red-orange color. It's also used in high-voltage indicators and vacuum tubes.
-
Argon (Ar): Argon is used in light bulbs to prevent the hot tungsten filament from oxidizing. It's also used in arc welding to protect the weld area from atmospheric gases.
-
Krypton (Kr): Krypton is used in certain types of photographic flashes for high-speed photography. It's also used in some types of fluorescent lights.
-
Xenon (Xe): Xenon is used in certain types of lamps, such as flash lamps and arc lamps, and in general anesthesia.
-
Radon (Rn): Radon is used in some types of cancer treatment, though its use is limited due to its radioactivity.
-
Oganesson (Og): Oganesson is a synthetic element, and its most significant use is in research.
These are just a few examples of how noble gases are used in various industries. Their low reactivity and other unique properties make them incredibly useful in a wide range of applications.

Describe the feature of noble gases that makes them highly unreactive.
Noble gases refer to the elements of Group 18 on the periodic table. These gases are commonly used in "neon lighting" because electric current passed through a sealed glass tube containing a noble gas causes the emission of photons of visible light at specific wavelengths (ie, colors) unique to the gas that is used.Atoms of the noble gases are energetically very stable due to having electron configurations with a full valence shell. This characteristic causes the noble gases to have very high ionization energies and electron affinities near zero. As a result, the noble gases usually do not participate in reactions with other elements. However, under special conditions it is possible to form a small number of noble gas compounds. For example, species that have a very high electron affinity (eg, fluorine) can pull electrons from some noble gas atoms to form a chemical bond. Reactions between F2(g) and Kr(g) or Xe(g) under reduced pressure can be achieved using an electrical discharge.Kr(g)+F2(g)−→−−−−electricaldischargeKrF2(s)Kr𝑔+F2𝑔→electricaldischargeKrF2𝑠Reaction 1Xe(g)+F2(g)−→−−−−electricaldischargeXeF2(s)Xe𝑔+F2𝑔→electricaldischargeXeF2𝑠Reaction 2A similar reaction can be achieved in a mixture of F2(g) and Rn(g) at an elevated temperature.Rn(g)+F2(g)−→−−400 °CRnF2(s)Rn𝑔+F2𝑔→400 °CRnF2𝑠Reaction 3The compounds formed from Reactions 1 and 2 are relatively stable and can be stored if shielded from water, heat, and light. Although the RnF2(s) from Reaction 3 is chemically stable, it still degrades over time because radon is radioactive and undergoes nuclear decay to become isotopes of Po, Bi, and Pb. In contrast, no stable fluorine compounds form when mixing F2(g) with He(g), Ne(g), or Ar(g). Question 35In the compounds formed in Reactions 1 and 3, the noble gas with the greatest electronegativity is:A.Kr, because it has a greater ratio of protons to neutrons in its nucleus.B.Kr, because it has fewer protons but its valence electrons are closer to its nucleus.C.Rn, because it has a greater total number of electrons.D.Rn, because it has a greater number of protons in its nucleus.
