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.
Generally methane (CH4) is called natural gas; but oxygen, nitrogen, noble gases, hydrogen sulphide, hydrochloric acid, etc. are natural gases.
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
The percentage of oxygen in air is 21%.
in number order it goes hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon, and radon. Hydrogen, nitrogen, oxygen, fluorine, and chlorine are diatomic gases. Helium, neon, argon, krypton, xenon, and radon are monatomic gases.
Carbon is a solid; oxygen, nitrogen and hydrogen are gases at room temperature.
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
Hydrogen, Nitrogen, Oxygen, Carbon and various noble gases
oxygen, nitrogen, hydrogen, fluorine
These gases are nitrogen, oxygen, argon, other noble gases, carbon dioxide, water vapors.
Hydrogen H2; nitrogen, N2; oxygen, O2; fluorine, F2; chlorine, Cl2
No. The only monatomic elements are the so-called 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.
Halogens, except for hydrogen, nitrogen and oxygen which are non-metals outside the halogen group.
Noble gases are used, especially the elements neon and sometimes argon
Nitrogen, oxygen, and neon are all elements on the periodic table. They are all gases at room temperature and are part of the same group/family on the periodic table, known as the noble gases.
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.
All of the noble gases, hydrogen, nitrogen, oxygen, fluorine, and chlorine.
