Question

Which is the most reactive metal?
• Iron
• Gold
• Zinc
• Potassium​

Answer 1

Answer:

Potassium

Explanation:

assium is highly reactive due to the following reasons

The ionization enthalpy of potassium is minimum.

It is the most electropositive and thus, most reactive metal.

It reacts vigorously with air as well as water.

The reactions are highly exothermic and hence, the hydrogen gas evolved as byproduct catches fire.
