Basically all the noble gases as they have a stable electronic configuration and therefore they would not share their electrons with other atoms.

Actually, the noble gases have been synthesized in labs to form noble gas compounds. Gold and platinum are both unreactive elements. There are probably more though.
You are most likely talking about the unreactive gases in the periodic table of elements. The Periodic Table of elements only contain elements (cannot be broken down into simpler substances).
In the periodic table, we have metals, non-metals and metalloids. Metals are usually solids in room temperature (other than Mercury). So the gases are in the non-metals section.
An unreactive gas would most commonly be found in group 18 (last column) on the periodic table of elements. These are the noble gases, and have 8 electrons on their outer shell, so they are very stable. Since they are stable, they are unreactive. They rarely react with other chemicals.
So the unreactive gases - group 18.(noble gases)
An nonreactive element in the Periodic Table of Elements is an element that has their last energy level (shell) filled with 8 valence electrons. Some examples of nonreactive elements are Helium, Neon, Argon, Krypton, Xenon, and Radon. Group/Family 18 (Noble Gas/Inert Gas Family) are all nonreactive elements.
All the noble gasses (Helium, Neon, Argon, Krypton, Xenon, and Radon) are very nonreactive. A few hundred compounds have been formed with noble gasses - mostly with Xenon and highly electronegative elements like Fluorine. Most of them require extreme conditions to form and are unstable. In general the noble gasses are considered inert and non-reactive.
Element which does not react with most acids or bases. Eg= Helium, Argon, Gold
helium as it has a full outer shell and its outer shell is very close to the nucleus
If you're talking about the elements in Group 18 of the periodic table, they're usually called the noble gases or the inert gases. These are pretty much the least reactive elements out there.
They are the noble gases. They include helium, krypton, radon and neon, among others.
Neon - one of the stable and unreactive elements of group 8.
Argon
Most elements are completely stable and safe. However, the safest elements would be the most unreactive. So, in that sense, the Inert Gases (exc. Radon, which is radioactive) are probably the safest group of elements, as they are completely unreactive.
copper meatal is so unreactive that some samples of copper exist in nature as the element itself. it is found native
Argon is a highly unreactive element. It can be used to displace air or oxygen in canned goods to prevent oxydation. Please see the link.
helium
Gold
Argon is the most unreactive in this series. Cheese is not an element; it is a mixture of compounds.
Calcium is a reactive chemical element.
Krypton is an unreactive gas.
*it has a filled valence shell
Because helium is an unreactive chemical element.
Absolutely not. In fact Gold is an unreactive element.
Neon (Ne) is a noble gas, very unreactive.
Inert.
Balls
Some element that is unreactive, like any of the rare gases helium, neon, argon etc.
