The potassium atom has a larger radius. When potassium loses an electron to become a cation (positively charged ion), it also loses the energy level in which the electron was. Therefore the potassium ion is smaller that the potassium atom.

potassium has a larger atomic radius than sodium because it has more electrons and thus can not hold the outer ones as firmly as sodium, as a general rule Atomic Radius increases on the periodic table increasing from right to left and also increasing from top to bottom

In case of Potassium atom, you have one extra electron in the outer orbit and after loosing it, you should have smaller size of Potassium ion. But then as the, electron is lost, there is net one extra positive charge in the atom, witch will pull the outermost (and all other orbits ) near the center of the nucleus making the size further smaller. But be ready for surprises. By this types of logic we can say that size of the Sodium chloride should be smaller than the size of the Potassium. But the actual size of both are found to be same.

How does it's atomic radius compare to that of krypton?

The element krypton's atomic radius is 189 pm. This is a measurement of its atom sizes or the distance between the electron cloud and the nucleus.


Does potassium or krypton have bigger atoms?

If by "bigger" you mean having more protons, then Krypton has more, and therefore is heavier, weighing in at 83.8 (atomic weight). Potassium weighs a mere 39.0983. However, if by "bigger" you mean how much space it takes up, the atomic radius of Potassium is 227 pm, as opposed to Krypton's radius of 88 pm. The atomic radius is the average distance from the nucleus to the outside boundary of the electron cloud. I'd go to the internet for more, but hope this helps anyway.

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 atom has the larger atomic radius K or Li?

K (potassium) has the larger atomic radius.


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 element has the largest atoms period 4?

Atomic radius decreases across a row (increasing positive charge in the nucleus causes electrons in the same energy level to "shrink" into the nucleus due to electrostatic attraction). This means that potassium has the largest atomic radius in period 4.
