1. Na and F,sodium is the most electro positive and F electronegative

Fr is the most reactive metal.
F is the most reactive nonmetal.
Therefore, the DEADLIEST reaction would occur between Fr and F ---> Option 4.
I hope that helps. :)

One will in basic terms talk backward and forward. for each action there's a reaction for each reaction there mus have been first the action. with a view to return to the element of beginning place then a reversal would desire to happen. this would take a chemical that would reason the reversal. In thought I answer hence

Caesium (or cesium) fluoride!!!!
Caesium = most reactive metal (NOT francium, as it will decay)
Fluorine = most reactive non-metal
Caesium = most reactive metal (NOT francium, as it will decay)
Fluorine = most reactive non-metal

1. Na and F
Fr would be more reactive than Na but Fr quickly decays with the longest isotope having a half life of about 20minutes.

I believe that among those, the answer is
(1) Using the equaiton:
2 Na + F2 --> 2NaF(solid)
It has an enthalpy(kJ) per mol product of 576.6, and enthalpy(kJ) per gram value of 13.73.
But I have been known to be wrong... from time to time. (I think that was C3PO speaking for R2D2...)
