what are noble gases chemistry?

Noble gas. The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold.

Inert gases are used generally to avoid unwanted chemical reactions degrading a sample. ... This is a tendency, not a rule, as noble gases and other "inert" gases can react to form compounds. The group 18 elements include helium, neon, argon, krypton, xenon and radon. They are referred to as noble gases or inert gases.

Neon Element Facts. The chemical element neon is classed as a noble gas and a nonmetal.
530462
It's one of the noble gases. There are seven noble gases: helium, neon, argon, krypton, xenon, radon, and oganesson (a synthetic element). Like the other noble gases, neon is colorless, odorless, tasteless, and under standard conditions, nonflammable.

Xenon (Xe), chemical element, a heavy and extremely rare gas of Group 18 (noble gases) of the periodic table. It was the first noble gas found to form true chemical compounds. More than 4.5 times heavier than air, xenon is colourless, odourless, and tasteless.

Inert gases, also known as noble gases, are monoatomic in nature. The simple reason for this is that they have completely filled octet which accounts for their high stability on their own. They don't have the necessity to bind with other atoms of their own kind to gain stability.

noble gas form compounds with oxygen and fluorine only because they are most electronegative elements. So they can ionise noble gases also.

Noble Gases They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds. This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons.

Updated June 06, 2018. A noble gas core is an abbreviation in an atom's electron configuration where the previous noble gas's electron configuration is replaced with the noble gas's element symbol in brackets. Writing an electron configuration using the noble gas core can save you a lot of time!
204524
All of the noble gases have full outer shells with eight electrons. ... At the top of the noble gases is little helium (He), with a shell that is full with only two electrons. The fact that their outer shells are full means they are quite happy and don't need to react with other elements.

All noble gases are colorless and odorless. They also have low boiling points, explaining why they are all gases at room temperature.
146757
All noble gases are non metals. All the noble gases except radon occur in the atmosphere. All these are gases. They are chemically unreactive.

These elements are most often found as monatomic gases, gases composed of particles (molecules) that consist of single atoms, such as helium. Noble gases were once believed to be unable to form bonds.

The rare gases, also known as the noble gases or the inert gases, are a group of six gaseous elements found in small amounts in the atmosphere: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). Collectively they make up about one percent of Earth's atmosphere.
183508
any of the gaseous elements helium, neon, argon, krypton, xenon, and radon, occupying Group 0 (18) of the periodic table. They were long believed to be totally unreactive but compounds of xenon, krypton, and radon are now known as the noble gases.

Answer: An inert gas is one that does not undergo chemical reactions. Noble gases refers to the right most group of the periodic table composed of helium, neon, argon, krypton, xenon, and radon. As you might have seen as an example in class, some noble gases can form chemical compounds, such as XeF4.

The 6 elements classified as "Noble Gases" are located in Group 18 of the Periodic Table. Because the outermost electron shell of atoms of these gases is full, they do not react chemically with other substances except under certain special conditions.
