 Electron configuration of a lofty gas

 The noble gases are elements contained in the viiians that have extremely high stability and are found in nature in a monoatomic form. The elements contained in the glorious gas helium (he), neon (ne), argon (ar), krypton, xenon (xe), radon (rn). These gases also occur in very little of the earth. In dry air there will be found a noble gas content as follows:



 Helium = 0.00052 %
 Neon = 0.00182 %
 Argon = 0.934 percent
 Krypton equals 0.00011 percent
 Xenon equals 0.000008
 radon

 But in the universe, helium is the most abundant of other noble gases, because helium is the fuel of the sun.

 * radon = very little in the atmosphere or in the air. And though discovered, it quickly turns into another element, for radon is radio active. And because of the very small amount of radon is also known as a rare gas supply.





 A glorious history of gas




 Legendary gas history begins with cavendish's discovery in 1785. Cavendish found a small section of air (kuarang of 1/2000) totally unresponsive despite the atmospheric gases.




 Then in 1894, Lord raleigh and Sir William ramsay succeeded in separating one of the elements of atmospheric gases (known today as noble gases) based on spectrum data. Then he tried to regulate the substance but was unsuccessful
