I do not have my reference table out to see the periodic table but in order to achieve the answer pull out the periodic table. You now know that this element is going to be a metal because it is a good conductor of electric and is malleable. Next you will find both cesium and radon and look in between them to see which one is a metal that has an atomic number that lies between both radon and cesium

<h3>What are spectator ions?</h3>
Ions that are not involved in the actual chemical reaction are called spectator ions.
A precipitation reaction occurs when two ionic compounds react to produce a precipitate and an insoluble substance which stays in the solution as a spectator ion.
Hence, Potassium and Nitrate ions are spectator ions in the reaction:
