Halogens have 7 valence electrons and nobel gases have 8.

Each atom wants 8 or none electrons according to the octet rule.

Therefore, nobel gases are relatively unreactive b/c they already have 8

Halogens only need 1 more valence electron, making them very reactive.

Which are more chemically reactive halogens or noble gases?

Halogens are more chemically reactive compared to noble gases. Halogens have a high tendency to gain an electron to achieve a stable electron configuration, while noble gases already have a full outer electron shell and are therefore less likely to react with other elements.


Why are the halogens most likely to react with the noble gases?

Halogens are highly reactive elements because they have seven valence electrons and are only one electron away from achieving a stable electron configuration like the noble gases. This electronic configuration makes halogens more likely to react with noble gases to gain that missing electron and achieve stability by forming compounds.


How do the properties of the halogens and noble gases compare?

They are completely different Noble gases are colorless, monoatomic gases; the halogens are diatomic, colored and there form at room temperature is F, gas, Cl, gas, Br, liquid I, solid. Nobel gases are chemically unreactive, helium and neon have no known compounds, a few very reactive compounds are known for the rest. The halogens are all reactive, fluoringe is the most reactive. One or more of the halogens will form compounds with all of the other elements apart from the noble gases. (apart from He and Ne)


Why is halogens more reactive than noble gas?

Halogens are reactive because they don't have a full octet. Noble gases are inert because they have a full octet. In order for a halogen to fulfill it's octet it must gain an electron. The electron usually comes from another atom such as sodium or another alkali metal but the electron can come from another source.


What do halogens and noble gases have very different chemical properties?

Halogens are highly reactive due to their tendency to gain an electron to achieve a stable electron configuration, while noble gases are already stable and do not readily react with other elements. Halogens are typically electronegative, whereas noble gases have very low electronegativity. This difference in reactivity and electron affinity leads to halogens forming compounds easily, while noble gases tend to exist as isolated atoms.

Why are the halogens so reactive and noble gases not reactive?

Because noble gases don't need to give or take any electrons - they have a perfect octet configuration. Where as halogens need to gain or lose electrons and will easily react to other halogens that need to lose or gain.


Is the carbon family or the noble gases more reactive?

the carbon family. the noble gases never react


Why are noble gases less reactive than halogens?

Noble gases have a full outer electron shell, making them stable and less likely to gain or lose electrons. Halogens, on the other hand, only need one more electron to complete their outer shell, making them highly reactive and likely to form bonds with other elements to achieve stability.


What groups are stable Alkali metals or alkanie metals or earth metals or halogens or noble gases?

Noble gases are the most stable group of elements due to having a full valence shell of electrons, making them generally unreactive. Alkali metals are highly reactive due to their tendency to lose one electron to achieve a stable electron configuration. Alkaline earth metals are less reactive than alkali metals, but more reactive than noble gases. Halogens are highly reactive nonmetals due to their tendency to gain one electron to achieve a full valence shell.


How is the halogen family and the noble gas family different?

The noble gases have completely filled orbitals and are hence generally stable and chemically inert. The halogens need one more electron to complete octet and are generally highly reactive.
