Explain your answer in terms of trends in the periodic table. Empirically measuring the radius of a single atom is a physically difficult task to accomplish and values vary from source to source. Lanthanide (10,012 words) exact match in snippet view article find links to article classification Nutrition Valence Data pages for elements Abundance Atomic radius Boiling point Critical point Density Elasticity Electrical resistivity. The correct order of the atomic radii of C, Cs, Al, and S is : (1) S < C < Cs < Al (2) C < S < Al < Cs (3) S < C < Al < Cs (4) C < S < Cs < Al. (Hint: See Sample Problem E.) Answer. Since there is not only an s and p-block between Rb and Cs, but also a d-block, wouldn't the increase in shielding between Rb and Cs be higher than that of Na and K? … And this is true; carbon has an average atomic radius … Li, Na, K, Rb, Cs are IA group elements from Li to Rb the atomic radius will be increased. An0n1m1ty. Atomic radius is the distance from the atom’s nucleus to the outermost electron orbital, and a lot of trends in the periodic table rely on this property due to its relationship to other atomic properties such as nuclear charge and shielding. Periodic Table properties. SURVEY . Q. en The last trend we could talk about is just atomic radius. For example, the atomic-ionic radius of chlorine (Cl-) is larger than its atomic radius. This measure of atomic radius is called the van der Waals radius after the weak attractions present … Tags: Question 35 . Rb, Sr, Cs, Ba. Does this periodic trend apply to any other group?
