An iodine atom has one more principal energy level than a bromine atom. Therefore the radius of an iodine atom is greater than the latter.
Smaller
18.96 times greater = 19.96 times as great.
Numerous elements exist as diatomic molecules in nature, including hydrogen, oxygen, nitrogen, chlorine, bromine, fluorine, and iodine.
Scandium empirical atom radius: 160 pm Scandium calculated atom radius: 184 pm
Refering to modern Peridic Table gas which is molecule are fluorine, chlorine, Bromine, Iodine and Astatine.
Iodine is the biggest atom among bromine, fluorine, chlorine and iodine as it has the highest atomic number and atomic radius.
Iodine is the largest atom among bromine, fluorine, iodine, and chlorine. It has more electron shells and a larger atomic radius compared to the other three elements.
The smallest radius from I Br Br I would be the bromine atom since it is closer to the central iodine atom compared to the outer iodine atom.
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 combining ratio of potassium and iodine is 1:1, meaning one atom of potassium will combine with one atom of iodine. The combining ratio of bromine and iodine is 1:1 as well, indicating that one atom of bromine will combine with one atom of iodine.

The formula for iodine monobromide is IBr. It consists of one iodine atom and one bromine atom bonded together.
Iodine's electron configuration is 2, 8, 18, 18, 7; bromine's is 2, 8, 18, 7. At the simplest level of modelling there is one more electron shell occupying space in an iodine atom than in one of bromine.
Iodine is a bigger atom than chlorine because it has more electrons and atomic radius.
IBr7 is the formula for iodine heptabromide.
Only those elements in group 7 on the periodic table are halogens like fluorine, iodine, chlorine, astatine and of course BROMINE
Its atom size is bigger than Chlorine but smaller than Iodine
