Question

What element has the symbol of Ar?

Answer 1

Hint : In the given question firstly we have to define what exactly is the symbol of Arand how can we determine it and give the proper definition and the characteristics of it. And we know that it belongs to an inert gas and the third most abundant gas in the atmosphere.

Complete Step By Step Answer:
The given question statement asks about the element that has the chemical symbol as Ar. We have to provide the basic definition and the other important characteristics for the element.
So basically the given chemical symbol belongs to the element of Argon which is indeed a Noble Gas and some basic knowledge of the gas of Argon is :
The element of Argon is a chemical element which has the atomic number of 18. It belongs to the group 18 of the modern day periodic table and is an inert or noble gas.We can say that Argon is the third-most abundant gas in the Earth's entire atmosphere which comprises 0.934% (9340 ppmv). It is also more than twice as abundant as the water vapor in the atmosphere. It is also 23 times as abundant as carbon dioxide (400 ppmv).
The Gas of Argon is well extracted industrially by the process of the fractional distillation of the liquid air. It is also mostly used as an inert shielding gas in the work of welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive.

Note :
Argon was first isolated from air in 1894 by Lord Rayleigh and Sir William Ramsay at University College London by removing oxygen, carbon dioxide, water, and nitrogen from a sample of clean air. They first accomplished this by replicating an experiment of Henry Cavendish's.
