Reactions like this one absorb energy because the reactants have less potential energy than the products.
<h3>What is an Endothermic reaction?</h3>
This is the type of reaction in which the reactants absorb heat energy from the surroundings to form products.
This brings about a decrease in the temperature as a result of the reactants having less potential energy than the products thereby making option B the most appropriate choice.

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
