What element X is most likely to react to form the compound XF5?
Which element (X) is most likely to react to form the compound XF5?
The options are:
- Carbon
- Antimony
- Chlorine
- Calcium
I initially thought it was helium, but I was incorrect since helium does not form a +5 oxidation state.

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 isnt Cl, calcium +2.
respond is Ca3X2. Na reacts with X and varieties Na3X. meaning that Na has valancy a million and X has valancy 3, so 3 atoms of Na reacts with a million atom of X to end its valancy. for that reason they type the ionic compound Na3X. similarly, all of us comprehend that Ca has valancy 2. So the ionic compound with X will could be Ca3X2, which shows that X has valancy 3.
