Answer 2

Answer:

Among the given metals, Potassium is exceptionally reactive.

...

• Reason
• The ionization enthalpy of potassium is minimum.
• It is the most electropositive and most reactive metal.
• It reacts with air as well as water vigorously.
• The reactions are highly exothermic and hence, the hydrogen gas evolved as byproduct catches fire.
