Atomic radius of Iodine is very large compared to potassium.
K (potassium) has the larger atomic radius.
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
Yes.
Iodine element is a halogen. Iodine has the atomic number 53.
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
Potassium. It has two extra shells than lithium.
Bromine has a SMALLER atomic radius because it has one more electron shell than Iodine. On the periodic table, atomic radius of an atom decreases across a period and increases down a group. Since Bromine and Iodine are in the same group, you know Bromine has a smaller atomic radius because it is in a lower period.
The atomic radius of potassium is 220pm.
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
K (potassium) has the larger atomic radius.
The atomic radius of bromine is bigger.

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.
Iodine has 53 electrons in its orbitals while fluorine only has nine. This does not even count the proton/neutron variance.
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
Smaller
The empirically measured covalent radius of tin is 145 pm; for iodine this radius is 140 pm.
