There are many gases that can be considered monatomic gases. Some of these gases are helium, neon, argon, krypton, xenon and radon and all of those gases are considered noble gases.

Which noble gas is monatiomic?
All noble gases are monatomic and exist as individual atoms.
Why are nobles gases special?
Noble Gases have an 'octet' which is a completely filled outer energy level with 8 electrons, except for Helium which has 2 valence electrons. This makes these gases in group 18 very stable.
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.
How many atoms does a monatomic have?
Monatomic means having 1 atom.
Is the noble gas xe monatomic?
Yes. All the noble gasses are monatomic.
Which noble gas is monatiomic?
All noble gases are monatomic and exist as individual atoms.
What type of molecules do noble gases form?
Monatomic Gasses. IT
Which element exists as monatomic molecules as stp?
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
What element always exists in monatomic form?
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
What are the three main features of noble gas?
They are all unreactive They are all gases They are all monatomic
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
What is a monatomic compound?
In physics and chemistry, monatomic is a combination of the words "mono" and "atomic," and means "single atom." It is usually applied to gases: a monatomic gas is one in which atoms are not bound to each other. At standard temperature and pressure (STP), all of the noble gases are monatomic. These are helium, neon, argon, krypton, xenon and radon. The heavier noble gases can form compounds, but the lighter ones are unreactive. All elements will be monatomic in the gas phase at sufficiently high temperatures. The only mode of motion of a monatomic gas is translation (electronic excitation is not important at room temperature). Thus in an adiabatic process, monatomic gases have an idealised γ-factor (Cp/Cv) of 5/3, as opposed to 7/5 for ideal diatomic gases where rotation (but not vibration at room temperature) also contributes. Also, for ideal monatomic gases: : the molar heat capacity at constant pressure (Cp) is 2.5 R = 20.8 J K-1 mol-1 (4.97 cal K-1 mol-1); : the molar heat capacity at constant volume (Cv) is 1.5 R= 12.5 J K-1 mol-1 (2.98 cal K-1 mol-1); where R is the gas constant.
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.
Is pure water monatomic molecular or lattice?
monatomic

What are mono atomic gases?
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.
