Which gas is present in clean air
Clean, dry air consists primarily of nitrogen and oxygen—78 percent and 21 percent respectively, by volume. The remaining 1 percent is a mixture of other gases, mostly argon (0.9 percent), along with trace (very small) amounts of carbon dioxide, methane, hydrogen, helium, and more.
Why is it called a noble gas
The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don’t react with anything. For this reason they are also known as inert gases.
Is hydrogen a noble gas
The noble gases (historically also the inert gases; sometimes referred to as aerogens) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity….Noble gas.HydrogenFranciumRadiumLawrenciumRutherfordiumDubnium5 more columns
Which noble gas is present in atmosphere

What air is made of
nitrogenEarth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
Which noble gas can diffuse through rubber and glass

What are the two main components of air
Standard dry air, which is mainly composed of three gases: nitrogen (about 78%), oxygen (about 21%), and argon (about 1%). Together, these three gases make up 99.96% of dry air.

RadonRadon (Atomic number 86) is a radioactive substance produced due to decay of Radium-226 found in Uranium ore. This is not present in the atmosphere.
What are the 7 noble gases
Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).
Which noble gas is more soluble in water

Who discovered inert gas
William RamsayThe Scottish chemist William Ramsay (1852–1916) is known for work that introduced a whole new group to the periodic table, variously called over time the inert, rare, or noble gases.
How does air support life
question_answer Answers(1) It contains oxygen which helps in respiration of all living organisms. It also contains carbon dioxide which helps in performing photosynthesis by plants. It contains nitrogen which is converted into usable form to be consumed by plants. Hence, air supports life.
