antimony. It has +3,+5,-3 so yeah. the others carbon+2,+4,-4, chlorine +1,+5,+7,-1 but -1 is the most often so it isn't Cl, calcium +2.

The element, x which is likely to react to form the compound xf5 is, Phosphorus, P.

The element x from the chemical formula xF5 should be an element with oxidation number 5+.

  • These elements include Nitrogen, Phosphorus, other group 5 elements and a host of transition metals.

  • Although, Nitrogen may exist in the +5 oxidation state, it only does so in amines.

  • However, Phosphorus on the other hand exists in the 3- electropositive metals but adopts the 5+ oxidation state when bonding with more electronegative elements such as Flourine, F in this case.

Ultimately, the element x which is most likely to react to form the compound xF5 is; Phosphorus.
