Question & Answer
Choose the Best Answer
Cs has the electron configuration [Xe] 6s1 and is used in atomic clocks due to its precise frequency.
Cs has the electron configuration [Kr] 5s1 and is primarily used in the production of batteries.
Cs has the electron configuration [Xe] 5s2 and is commonly employed in the manufacturing of glass.
Cs has the electron configuration [Xe] 6s1 and is utilized in fertilizers for its low reactivity.
Understanding the Answer
Let's break down why this is correct
Cesium’s electron layout is [Xe] 6s1, meaning it has one electron in the outermost shell. Other options are incorrect because The idea that cesium’s core is [Kr] 5s1 mixes up krypton and a wrong shell number; Saying cesium has [Xe] 5s2 suggests it has two outer electrons and uses glass, which is not true.
