Noble gases or the inert gases as they are become know as have a full outer shell. It is possible to get different elements to fill in the last outer shell but it is extremely difficult to take electrons from a noble gas therefore when you ask what the difference is the question is perhaps not phrased properly because there is no difference they are two different categories. A noble gas is an element with a full outer shell and full outer shell is when an element has filled all of the max electrons in the last orbital.
Metalloids do not have a complete outer shell, as they have properties that are intermediate between metals and nonmetals. They typically have three, five, or six electrons in their outer shell, which gives them characteristics of both metal and nonmetal elements.
Helium is the element in the noble geses family that does not have an octet. Helium is the element in the noble geses family that does not have an octet.
Noble gases are considered noble because they are stable and have a full outer electron shell, making them very unreactive. This full outer shell makes them less likely to form chemical bonds with other elements.
For most elements, a complete outer shell, like that of a noble gas, has eight electrons. There are exceptions. Helium, which is the most noble of the noble gases, has only two electrons in its outer shell. A few other light elements only need two (and hydrogen can also exist with no electrons at all, in the form of a naked proton, which is also a form of completion for the outer shell).
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.
Helium is the only noble gas that does not have eight electrons in its outer shell. It has only two electrons in its outer shell.

Every noble gas does have an outer shell. That's why they don't want to react with any other element. This is because they don't want to gain or lose any electrons. Because they have a full outer shell.
Argon has eight valence (outer) shell electrons. It is a Noble Gas so its valence shell is full (Octet Rule).
The noble gases
Eight. Neon is one of the Inert (also know as the Noble) Gases. The Inert Gases are largely unreactive, due to their filled outer shell.
Noble gases are considered noble because they are stable and have a full outer electron shell, making them very unreactive. This full outer shell makes them less likely to form chemical bonds with other elements.
Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
