which element would most likely combine with flourine? argon, neon, krypton or helium?

Answer 1

Any element except helium,neon,argon will react with flourine.
In case of your question Krypton is the answer.
But the condition required are extreme and the compoun is unstable.
Example-Krypton difluoride

Heavier noble gas like xenon and krypton react with flourine to form clathrate compounds.


Xenon can even be reacted with oxygen.

Although NO COMPOUNDS OF HELIUM, NEON, ARGON are possible.

Answer 2

While all of these are noble gases and therefore have a noble gas electron configuration (i.e. 2 s and 6 p electrons in the outer shell, excepting He), the heavier noble gases can take alternative electron configurations using the unoccupied d-orbitals. Theoretically, even Argon might, but Krypton definitely will do so. Neon and Helium have no such d-orbitals available and are completely inert.

Answer 3

Som's right.

Given the right conditions,
fluorine (itself being reactive) will react with Krpyton,
though not the first three noble gases (helium, neon, argon).

Answer 4

Definately Krypton. The further down the noble gas column you progress, the more the elements will react.

Answer 5

in theory, SOM is correct.

in real life however, the situation is different.

noble gases are indeed inert, but to say that some of them will never form compounds is too harsh and rather myopic in my pov. we are dealing with science here. anything is possible given time.

the compound HeNe has been produced (from an electric arc) and documented before. so has HArF. these two compounds, stable or not, are proof that the 3 smallest noble elements are capable of forming compounds.

that said, to answer the question as to which of the noble elements will best react with fluorine, the obvious route to solve it is to look at the ionisation energies. you should look for the lowest number. this corresponds to krypton, because it has the largest atomic radius (reduced nuclear charge on valence e's).

Answer 6

The three elements have electronic configuration ending in 8, means they are octet are complete. They belong to noble gases. These are assumed to be unreactive so tey are called noble gases.

Answer 7

i would say helium, it has the least number of shells so i think it would be most reactive

Answer 8

Since all are noble gases...it would be ALMOST impossible for any of them to react with ANY element.

However, under certain conditions, i feel it would be....neon.
