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.

Is the atomic radius of potassium larger than of calcium?

Yes, the atomic radius of potassium is larger than that of calcium. This is due to potassium having one more electron shell than calcium, leading to a larger atomic radius.


How does calcium atomic radius compare to magnesiums radius and potassiums radius?

Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.


Which atom has the larger atomic radius K or Li?

K has a larger atomic radius than Li. This is because atomic radius generally increases down a group in the periodic table, so potassium (K) being below lithium (Li) in Group 1 will have a larger atomic radius.


Which element has larger raduis between potassium and calcium?

Potassium has the larger radius (not raduis!).


Which of these elements has the largest atomic radius. Aluminum potassium fluorine. Calcium?

Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.


Which is bigger the atomic radius of potassium or atomic radius of iodine?

The atomic radius of iodine is larger than the atomic radius of potassium. This is because as you move down a group in the periodic table, atomic size increases due to the addition of more electron shells. Iodine is located below potassium in the periodic table, hence it has a larger atomic radius.


How does calcium's atomic radius compared to magnesium radius and potassium radius?

The atomic radius of calcium is larger than magnesium but smaller than potassium. This trend is consistent with the periodic trend across Group 2 elements where atomic radius increases down the group due to additional electron shells. Additionally, going across a period from left to right, atomic radius decreases due to increasing nuclear charge pulling electrons closer.


How does potassiums atomic radius compare to that of sodium?

Potassium has a larger atomic radius compared to sodium. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of more energy levels. In the case of potassium and sodium, potassium is located below sodium in the same group, resulting in a larger atomic radius for potassium.


Which one has the larger radius potassium ion or bromide ion?

The bromide ion has a larger radius than the potassium ion. This is because bromine has more electron shells than potassium, resulting in a larger atomic radius and thus a larger ionic radius for bromide compared to potassium.


What has larger atomic radius potassium or bromine?

Potassium has a larger atomic radius compared to bromine. This is because atomic radius generally increases as you move down a group in the periodic table, and potassium is located in a lower group (Group 1) compared to bromine (Group 17).


What atom has the largest atomic radius calcium iodine potassium or cesium?

Cesium has the largest atomic radius among calcium, iodine, potassium, and cesium. It is located at the bottom of the periodic table in Group 1 (alkali metals), and as you move down a group, atomic radius increases due to additional electron shells.


Which has the greatest atomic radius K or Ca?

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.
