Answer: Option C) potassium
Explanation:
According to the reactivity series of metals, potassium K is the most reactive and electropositive metal. it is followed by sodium Na, Magnesium Mg, and Calcium Ca.
Thus, the descending order of reactivity is as follows: K > Na > Mg > Ca which makes potassium displaces the less reactive elements from their respective solutions during chemical reactions.
Answer:
it prevents leakage of water
This is a chemical property due to radioactivity being a chemical characteristic of uranium. This fact describes its chemical structure.
