Both atoms have the same van der Waal's radius (2.00) Radii that are not available in either of these publications have RvdW 2.00 A. However, Caesium has a greater covalent radius (1.67) as compared to that of Radon (1.50) See the link for more info.

Which element is the largest K Rb Na Li?
Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
Why is the atomic radius of potassium larger than calcium?
Although they are all group I atoms, Na and K have a nuclear charge representative of s,p,and d electrons. Once you get to Rb the 4f sublevel comes into play along with the significantly increase nuclear charge. As a result, the does not increase as significantly as the Na and K.
What is the area of a 10km radius in square km?
314.16 square k,.
What is the atomic and mass number of potassium?
The atomic number is 19 and the mass number of its most abundant isotope K-39 is 39 (19 protons + 20 neutrons) while the mass of that isotope is 38.96371 a.m.u.The relative atomic mass of the element potassium, K, is 39.10 g/mole.
The correct symbol for the isotope of potassium with 22 neutrons is k 41 19?
An isotope of potassium with 22 neutrons has an atomic number of 19 and atomic mass of 41. The symbol is K with a subscript 19 and superscript 41.
Largest atomic radius out of Ca Na Fe Al and k?
K
Which atom has the larger atomic radius K or Li?

Smallest to largest atomic radius PotassiumMagnesiumCalciumRubidium?
mg, ca,k ,rb magnesium, calcium, potassium, rubidium as you do down a group atomic radius increases as you go across a period atomic radius decreases
Does na1 have a larger atomic radius than k1?
K+ has larger radius
Which of the following has the largest radius K plus Na plus Na or K?
Potassium has the largest atomic radius.
How does the presence of core electrons affect the atomic radius of elements?
When there is an anion (negative charge) the radius will be larger because it is more full whereas it will be smaller if it is a positive charge because of less electrons. ex largest to smallest radius (K-,K, K+)
What has the largest radius K or Na?
Postassium, K, has a larger radius than sodium, Na, because it is in the next period on the table but in the same group as sodium.
Which has the smallest radius K Rb K Rb?
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
What has the greatest radius Cs Fr K Li?
Francium (Fr) down a group, the radius increases.
