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 greater atomic radius than Krypton. This is because atomic radius generally decreases across a period from left to right on the Periodic Table, and Potassium is located in the far left group (Group 1) while Krypton is in the far right group (Group 18).
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.
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.
The element in period 4 with the smallest atomic radius is argon. It has a smaller atomic radius compared to the other elements in period 4 because it is a noble gas with a full valence shell, resulting in a small atomic size.
The atomic radius of sodium (Na) is smaller than the atomic radius of potassium (K). Sodium has a smaller atomic radius because it has fewer electron shells compared to potassium.
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.
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.
