Question

Name the element that has not yet been reacted with ${\mathrm{F}}_2$?

Answer 1

The element that has not yet been reacted with${\mathrm{F}}_2$:

• The compound of Fluorine with other elements or groups is generally known as Fluoride.
• All The noble gases except for Argon has found to have formed respective Flouides i.e ${\mathrm{XeF}}_2,{\mathrm{XeF}}_4.$
• But $\mathrm{Ar}$ is the only known element that has not yet reacted with ${\mathrm{F}}_2$ to form any compound.
• This is due to the reason that it is more stable than the other noble gas elements i.e $\mathrm{Xe},\mathrm{Kr},\mathrm{and}\mathrm{Rn}.$
• Hence, there is no compound of $\mathrm{Ar}$ yet been reported with Fluorine.

Thus, the element that has not yet been reacted with ${\mathrm{F}}_2$ is $\mathrm{Ar}$(Argon).
