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.
What else can I help you with?
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.
The most abundant gases are nitrogen and?
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
What proportion of each gas in air?
The percentage of oxygen in air is 21%.
What gases are on the periodic table?
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.
Are nitrogen hydrogen oxygen and carbon all gases at room temperature?
Carbon is a solid; oxygen, nitrogen and hydrogen are gases at room temperature.
What are the two main gases?
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
What element is in the fog?
Hydrogen, Nitrogen, Oxygen, Carbon and various noble gases
Name 2 gases other than the 6 noble gases?
oxygen, nitrogen, hydrogen, fluorine
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 do nitrogen oxygen and neon all have in common?
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.
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 moleclues are in a gas state at room temperature?
All of the noble gases, hydrogen, nitrogen, oxygen, fluorine, and chlorine.
