Question

Write any three uses of Neon.

Answer 1

Hint: To write the uses of neon, we should first know about neon. We should know that neon is the fourth most abundant element in the universe, only 0.0018% of the earth's atmosphere is neon.

Step by step answer:
So, first of all we should know about neon. We know that neon is a noble gas and has been assigned atomic number 10 and it is present in group 18 of the periodic table. It is present in a noble group of gases. We should know that it is chemically inert gas and non-toxic in nature. It should be noted that, there is no threat to the environment and has no impact since it is non-reactive and does not form compounds. This gas has no ecological damage. We should know that Neon was discovered by British chemist Sir William Ramsay in 1898. We should know that Neon is the second lightest inert gas.
Now, we will discuss about some uses of Neon:
- The vibrant advertising signs on shops that we see in market streets have neon gas filled in it. We should know that the reddish-orange coloured neon lights are used in making these advertising signs. The tube lights that we called neon lights are generally made up of different noble gases or varied colours of fluorescent lighting. We also use neon gas with other mixed noble gases.
- We should know that, uses of neon include lightning arrestors, high-voltage indicators, television tubes and meter tubes. It is also used in vacuum tubes and helium–neon lasers.
- We should know that liquefied form of neon is commercially used as a cryogenic refrigerant. We should note that neon is required when it doesn't require the lower temperature range that is attainable with more extreme liquid-helium refrigeration.

Note:
- We should note about one important application of neon and helium. We should know that mixture of helium and neon is used for respiration by marine divers in the sea since helium is less soluble in blood than nitrogen at high pressure.
- We should know that liquefied neon is relatively expensive – for small quantities, the price of liquid neon can be more than 55 times that of liquid helium.
