A monatomic gas is a gas that "hangs around" in the form of single atoms. Let's take a little journey to get where we need to go. The funny thing about a lot of gases is that they are what is called diatomic. You've heard of oxygen and you've also heard it called "O2" in a lot of instances. That's because oxygen atoms in the air cruise around in a "buddy system" with another atom of their own kind. We know that nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2) and the like all operate as diatomic molecules. But what about monatomic gases? It is the inert gases or noble gases that hang around in the air as single atoms. Their nature is that they don't want to "hook up" with anything else; they don't want to form compounds. And they are monatomic gases when we encounter them. You'll recall that the monatomic gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They are all in Group 18, and appear in that order from the top to bottom of that group.

Is hydrogen mono atomic?
No. Hydrogen exists as a diatomic gas.
What type of bond is argon?
The argon molecule is mono-atomic and so there is no bond.
What is barium mono-atomic cations and anions?
Barium forms a divalent cation and no anions.
Why inert gases occur in atomic form?
to get stability
What is the name of group 18 elements in the periodic table?
it is 35
Are all noble gases mono atomic?
Yes. all are mono atomic
What are the examples of mono atomic elements?
All of the metallic elements and the noble gases are normally mono-atomic.
What is a mono atomic gases?
The noble gases, e.g. helium, argon, neon, etc. are monoatomic gases.
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.
What compounds do not contain molecules?
Mono atomic gaseous elements of noble gases (group 18)
Is nitrogen and oxygen mono atomic?
No. The only monatomic elements are the so-called noble gases.
What kind of noble gas is monatomic?
All noble gases are mono atomic at room temperature
Why is the specific heat of poly atomic gases is higher than that of mono atomic gases?
Diatomic gases can absorb heat to increase their vibrational and rotational energy in addition to their translational energy. Monatomic gases have no bonds to vibrate or rotate.
Why are inert gases mono atomic?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions and are mono atomic
Is the molecule of a noble gas the same as the atom of a noble gas?
Yes. as all noble gases are mono atomic.
Who discovered mono-atomic ions?
who discovered the mono-atomic ions?
Why the forces of attraction in noble gases are weak?
Noble gases are mono atomic and are non polar. They are hence held together by van der Waals forces of attraction which is a weak force of attraction.
