cesium rubidium potassium sodium

Answer 2

Based on the group 1,the radius of sodium < potassium
Caesium have highest number of proton among others and hence,high number of electron.So,the number shell of caesium become increase.And Caesium has largest atomic radius.

Answer 3

In this case, Cesium has the largest atomic radius. Because the atoms get bigger as you go down groups.

Answer 4

I think you mean Caesium. And the answer is Caesium. The closer to the bottom right an element is, the greater it's radius, mass, etc. Basically it works like this:



1,2,3,4,5

2,3,4,5,6

3,4,5,6,7
