Be + F2 --> BeF2
---------------------
The ionic compound beryllium fluoride.
There is no such thing as a compound element. Something cannot be both an element and a compound Neon is an element and so is made of nothing but neon. Neon does not form any compounds.
Elements dont react to form other elements. However, compounds can react with one another or decompose to form elements. More importantly, fluorine is a diatomic molecule, which means that it will never exist as "F" but always as F2.
F2 is a neutral diatomic molecule, it often reacts to form compounds that have a fluoride F-, ion.
It is still dangerous in some of its compounds. That said though, one of the reasons it is dangerous in its pure form is that it is so highly reactive. (Incidentally, fluorine exists in molecular form, F2, rather than elemental form, F.)
If the compounds are polar covalent then they are soluble in water . If they contain high electronegative element like F,O and N ,water can form inter molecular hydrogen bond with those compounds.
P, the element is Carbon.
Fluorine is an element, the symbol F would indicate its atomic form not a molecule, the symbol F2 would indicate its diatomic molecular form. Fluorine gas is the F2 diatomic molecular form not F.
No, they would form an ionic bond.
None. Helium does not form any compounds. Theoretically, true compounds may be possible, such as helium fluorohydride (HHeF) which would be analogous to HArF, discovered in 2000. This requires very low temperature (< 2.5K) and extremely high pressure (> 23GPa). The existence of fluoroheliate anion (F-HeO-) is suspected.
Perflourinated compounds are organic fluorine compounds with bonds C-F and C-C.

If yoy think to diatomic (atoms of same element) molecules: O, N, Cl, F, Br, I, H.
