Fr; Francium
Francium is more reactive than potassium.
Francium is more reactive than sodium.
K; Potassium
Potassium is more reactive than sodium
The first ionization energy is lower.
Francium is more reactive than potassium.
Francium is more reactive than sodium.
No. Francium is a Group I element, and it is extremely reactive ... explosively with water ... more than potassium and sodium. It will be oxidized of one electron.

Sodium, which closely follows potassium, as the attached link reveals. This is for common metal only. Rubidium and Cesium are far more reactive. Francium is even more so but is radiocative. Strictly speaking the answer is Cesium
Francium is more reactive.
Sodium
Francium is considered more reactive than Chlorine.
Iron rusts with water the more reactive metals react for the oxygen in a displacement the less reactive metals there is no reaction hope this helps x
