The term noble is old and today inadequate.
The so-called noble gases have the outer electron shell full, with 8 electrons; this structure lead to a very low chemical reactivity but now they are not all considered as inert elements.
Compounds have been made with Krypton, Xenon and Radon. None have yet been made for Argon, Neon or Helium.

The percentage of oxygen in air is 21%.
What impurities are found in helium?
This depends on the preparation method and the quality of helium; generally traces of oxygen, nitrogen other noble gases.
What are examples of natural gas?
Generally methane (CH4) is called natural gas; but oxygen, nitrogen, noble gases, hydrogen sulphide, hydrochloric acid, etc. are natural gases.
How can you justify that air is a homogenous mixture. Identigy substances present in it?
Air is a mixture of nitrogen oxygen co2 noble gases and water vapours
What are the most two common gases in air?
Nitrogen and Oxygen are the most common gases in the atmosphere.

oxygen, nitrogen, hydrogen, fluorine
Why oxygen nitrogen exist in molecular state?
All gases exist in molecular form except noble gases.
What are the gases that makes up the air?
These gases are nitrogen, oxygen, argon, other noble gases, carbon dioxide, water vapors.
What are the Five gases that are not noble gases?
Hydrogen H2; nitrogen, N2; oxygen, O2; fluorine, F2; chlorine, Cl2
Is nitrogen and oxygen mono atomic?
No. The only monatomic elements are the so-called noble gases.
What is the most unreactive element besides the noble gases?
N2, nitrogen is about 78% in air but does not take part in several reactions as oxygen does so we can say that after noble gases Nitrogen is the least reactive gas or element.
What are the gases which aren't noble gases called?
Halogens, except for hydrogen, nitrogen and oxygen which are non-metals outside the halogen group.
What groups is used in neon lights. is it halogens or nitrogen group or oxygen group or noble gases. which one is it?
Noble gases are used, especially the elements neon and sometimes argon
What is air made up of?
air is made up of some gases. i.e. it's made up of hydrogen, nitrogen, and mixture of other gases. but the most common is it is made up of nitrogen-78%, oxygen-21%, and other gases-1%air is made up of different gases such as oxygen, carbondioxide, nitrogen and noble gases.
What are the four most abundant gases in dry air?
100% Nitrogen, 321% oxygen, 1% Argon and Carbon Dioxide. The four most common gases in dry air consist of nitrogen, oxygen, argon, and carbon dioxide. Nitrogen and Oxygen make up most of dry air.
