WebbThe radius increases sharply between the noble gas at the end of each period and the alkali metal at the beginning of the next period. These trends of the atomic radii (and of various other chemical and physical properties of the elements) can be explained by the electron shell theory of the atom; they provided important evidence for the development and … WebbThe smallest atom on the periodic table is helium, He, and has a radius of 31 pm. Yeah, He is even smaller than hydrogen, H, which is 53 pm. Which atom is the largest? That would be cesium, Cs, which comes in with a radius of 343 pm. So that is roughly a 10:1 ratio of largest to smallest. the princess diaries streaming
