Noble gases are generally chemically inert, because they have completely filled valence orbitals. However, the nucleii of the heavier ones have a weaker electromagnetic 'hold' on the electrons of their outer shells. This means extremely powerful oxidising agents can react with the heavier noble gases, such as Platinum hexafluoride reacting with Xenon to form Xenon hexafluoroplatinate.

Noble gases have a full outermost shell and thus they are stable (not reactive).

Noble gases have completely filled orbitals, hence they are stable and generally chemically inert. Metals have incompletely filled orbitals, hence they are generally reactive.

Is noble gases metals that are more reactive than the transition elements but less reactive than the alkali metals?

No, the noble gasses are nonmetals that are less reactive than all other elements.


Is the carbon family or the noble gases more reactive?

the carbon family. the noble gases never react


Which are more chemically reactive halogens or noble gases?

Noble gases have completely filled orbitals and hence are generally chemically inert. Halogens are highly reactive as they need one more electron to complete octet.


How does metals or nonmetals change as you go down group 0?

As you go down Group 0 (also known as the noble gases), both metals and nonmetals tend to become less reactive. The noble gases are already very stable and unreactive, and this reactivity decreases even further as you move down the group. Metals in Group 0, called alkali metals, also become more reactive as you go down the group, while nonmetals in Group 0, known as halogens, become less reactive.


What is the rule for the activity trends of metals and nonmetals?

Metals: the farther to the left the more reactive they are. Group 1 metals, which include sodium and potassium, are so highly reactive that they do not exist in nature by themselves (only in compound form.) Non-metals: the farther to the right the more reactive they are *with the exception of group 18* which are the noble gases and do not react at all. The most reactive are group 17, which include fluorine and chlorine. These non-metals, like group 1, rarely exist by themselves because of their high reactivity.

Is chlorine more reactive with oxygen than argon?

Yes. Argon is one of the noble gases with a valence configuration of 8 electrons. All of the noble gases are the least reactive elements.

Do gold and silver have reactivity?

Gold and silver are noble metals; gold is not so reactive, silver is more reactive.


How many electrons away from a noble gas are the alkali metals?

Alkali metals have one electron more than the noble gases.

Why noble gases react with fluorine as you know noble gases are more stable?

Because fluorine is having the most electronegativity and is the most reactive non metal.


Which group of elements is very stable and nonreactive?

The class of noble gases (Helium, Neon etc. in group 18) There are two groups that come to mind when talking stability: the noble gases and the coinage metals. The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are very chemically stable and do not readily form compounds. Note that although Radon is chemically stable, it's not stable from a nuclear standpoint and will decay (but it is not reactive in the chemical sense). The coinage metals (such as gold, silver, and copper) are very unreactive. Note that the further an element is from Au on the periodic table, the more reactive it is (obviously the Noble gases do not follow this trend).

Where are the noble gases located on the periodic table and what does their position reveal about their reactivity?

the noble gases are positioned on the last column on the right. As the elements descend down the column they are more reactive


Is the barium ion or atom more chemically reactive?

All the neutral atoms (except noble gases) are more reactive. To gain stability, they form ions; therefore, ions are less reactive.
