where are the noble gases on a periodic table?
73108
Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

Noble gases like He, Ne, Kr, Xe and Rn are placed in a separate group because of the following reasons: - They are extremely unreactive. - They donot combine with any other element of the periodic table. - All the noble gas elements have zero valency and placed in zero group with similar chemical properties.
149237
Noble gases are placed in a separate group of the periodic table because they are inert elements. They are unreactive as their valence shells are completely filled with electrons. Their properties are different when compared to all the other elements.

Group 18: Noble Gases Group 18 elements are nonmetals called noble gases (see Figure below). They are all colorless, odorless gases. Their outer energy level is also full, so they are the least reactive elements.
406745
Noble gases are the elements that belong respectively to group 18 . What do they all have in common? Well, since they are the very last group on the periodic table, they have full outer shells of valence electrons.

The noble gases are present in the atmosphere in small amounts: 0.934% Argon. 0.0018% Neon. 0.00052% Helium.

Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a gas. Argon is classified as an element in the 'Noble Gases' section which can be located in group 18 of the Periodic Table.

The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.

The non-metals or non-metallic elements; hydrogen (H), carbon (C), nitrogen (N), oxygen (O), phosphorus (P), sulphur (sulfer) (S), selenium (Se), (Uuo may belong here) and the noble gases form a relatively small group with a step like pattern towards the left-hand side of the periodic table (hydrogen being the odd one ...

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.
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.

Noble gas. ... Other characteristics of the noble gases are that they all conduct electricity, fluoresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant environment. This chemical series contains helium, neon, argon, krypton, xenon, and radon.

Oxygen is not a noble gas. Oxygen is a gas in the group 6 of the periodic table which needs 2 more electrons to complete the outermost shell. ... The noble gases are Helium, Argon, Neon, Xenon, Krypton and Radon . These are the only elements that can exist in atomic form without being highly reactive.

There are seven noble gas elements: helium, neon, argon, krypton, xenon, radon, and oganesson. Noble gases are the least reactive chemical elements. They are nearly inert because the atoms have a full valence electron shell, with little tendency to accept or donate electrons to form chemical bonds.
165882
A noble gas is different from other elements because its highest electron energy level is completely filled. The examples of noble gases are helium, neon, Argon , krypton,Xenon , radon.

Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
909958
The noble gases are in Group 18 (8A). 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. ... Because this configuration is extremely stable as well as symmetrical, the noble gases are very unreactive.
