Yes. all are mono atomic
Yes. as all noble gases are mono atomic.
The noble gases from the least atomic number are, helium, neon, argon, krypton, xenon and redon.
Yes. All noble gases are 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.
Noble gases are a category and exist as a Group (VII or 0) in the Periodic Table. They are helium (He) to radon (Ra) To add to the above, there are six nobel gases - Helium, Neon, Argon, Krypton, Xenon, Radon - He, Ne, Ar, Kr, Xe, Rn. All have a complete outer energy shell and are considered to be essentially inert, which means they do not react readily with other elements.
All noble gases are mono-atomic and 1 mole of each element will have 6.023 x 1023 atoms.
All of the metallic elements and the noble gases are normally mono-atomic.
All noble gases are mono atomic at room temperature

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.
All noble gases are gases in their standard state
The atomic mass increases as you go down the group of Noble Gases.For example, helium is the first on down the group of Noble Gases. If you have a balloon full of helium, it would rise as it's atomic mass is the lightest of 4.002602 amu. Then, the furthest down the group of noble gases is radon. If you have a balloon full of radon, it would sink down immediately as it's atomic mass is 222.0 amu.
Noble gases have a full outer shell of electrons, which makes them stable and unreactive. For noble gases, the outer shell typically contains eight electrons, following the octet rule. This applies to all noble gases with atomic masses greater than three, such as neon, argon, krypton, xenon, and radon. Therefore, a noble gas with an atomic mass greater than three has eight electrons in its outer shell.
