Argon is a noble gas with a complete valence electron shell, which makes it chemically inert and stable as a single atom, or monoatomic. In contrast, nitrogen has five electrons in its outer shell and needs to share three electrons with another nitrogen atom to achieve stability, resulting in the formation of diatomic nitrogen (N₂) molecules. This difference in electron configuration and bonding behavior explains why argon exists as monoatomic while nitrogen exists as diatomic.
What else can I help you with?
What is helium's most common diatomic bond?
None. Helium has completely filled orbitals it is stable and chemically inert (non-reactive). So, helium exists as mono atomic and not as a diatomic species.
Are all noble gases mono atomic?
Yes. all are mono atomic
Why molar specific heat of diatomic gas is larger than that of mono atomic gas?
The molar specific heat of diatomic gases is larger than that of monatomic gases because diatomic gases have more degrees of freedom. While monatomic gases can only store energy through translational motion, diatomic gases can store energy in translational, rotational, and vibrational modes. This additional ability to rotate and vibrate requires more energy, resulting in a higher molar specific heat for diatomic gases compared to monatomic gases.
Why is the molar specific heat of the diatomic gas usually larger than that of mono-atomic gas?
A monatomic gas has no contribution from vibration to its specific heat. A diatomic gas has both vibration of the two atoms as the stretch and compress the bond between them and can rotate faster or slower. With more ways to store energy than just translational energy, diatomic gases tend to have higher heat capacities.
Who discovered mono-atomic ions?
J.J. Thomson discovered monatomic ions in 1897 during his experiments with cathode rays. These ions are formed when atoms gain or lose electrons to achieve a stable electron configuration.
What are the other gases found in the periodic table?
Mono-atomic gases: Helium, neon, argon, krypton, xenon, and radon. Di-atomic gases: Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine.
Where is argon geographicaly located?
Argon is a mono atomic chemically inert gas and is found only in the atmosphere.
What is the atrractive force between argon atoms in liquid argon?
Argon exists as mono atomic species. The force of attraction will be van der Waals forces of attraction between the argon atoms.
What is a mono atomic gases?
The noble gases, e.g. helium, argon, neon, etc. are monoatomic gases.
Is lead a mono atomic element?
Yes it is. Lead is never found as Pb2 the diatomic condition. This is usually found in the halogens; nonmetals.
What is helium's most common diatomic bond?
None. Helium has completely filled orbitals it is stable and chemically inert (non-reactive). So, helium exists as mono atomic and not as a diatomic species.
Is nitrogen and oxygen mono atomic?
No. The only monatomic elements are the so-called noble gases.
What is colour of argon gas?
Argon is a mono-atomic colorless gas exhibiting an lilac/violet glow when placed in a high voltage electric field (as in gas-discharge lamps)
Is chlorine mono- atomic at some temperatures and diatomic in others?
It's diatomic at room temperature. I have never heard of actual monoatomic chlorine, maybe some physicist created some in a lab at incredibly low or high temperatures, but I would say it is diatomic for all intents and purposes.
Which of the gases in the earth's atmosphere would you expect to find as molecules and which as individual atoms?
In Earth's atmosphere, you would expect to find gases like oxygen (O2), nitrogen (N2), and hydrogen (H2) as molecules, which are composed of two or more atoms bonded together. Gases such as helium (He), neon (Ne), and argon (Ar) are present as individual atoms since they are noble gases that exist as single atoms and do not typically form molecules in the atmosphere.
Is hydrogen mono atomic?
Yes, hydrogen is a diatomic molecule under normal conditions, meaning it exists as H2, containing two hydrogen atoms bonded together. However, in certain conditions, hydrogen atoms can exist as monatomic species, such as in the form of atomic hydrogen.
Is sodium mono atomic or diatomic?
Sodium is a monoatomic element, meaning it exists as single atoms in its elemental form. Each sodium atom has one electron in its outer shell.
