The empirically measured covalent radius of tin is 145 pm; for iodine this radius is 140 pm.
Smaller
Iodine is a non metal element. Atomic mass number of it is 127.
The atomic mass of iodine is less than the atomic mass of all elements with greater atomic number.
Ni (Nickel) has a larger atomic size than Fe (Iron). This is because Nickel has more electrons and energy levels, which leads to a greater atomic radius compared to Iron. Additionally, Nickel is located in the same period as Iron on the periodic table, but it is to the right of Iron, indicating a larger atomic size.
It might be Iodine and Tellurium because Tellurium has a larger atomic weight than Iodine but Iodine has more similar properties with Fluorine and Chlorine so Mendeleev placed them that way to make more sense but at that point the elements were aranged in order of atomic mass. Now the periodic table is in order of it's atomic number rather than it's atomic mass so it all fits nicely.
Smaller
Iodine gains one electron to form iodide ion. The size of iodide ion is larger than the size of iodine atom.

due to increase in anion size. Iodine is larger than chlorine. see Fajan's Rules.
i believe it is 57 do.If im wrong then im wrong im very sorry if i am.
In terms of atomic radius yes, nitrogen is larger than fluorine. However, the common fluorine isotopes have a greater mass than those of nitrogen.
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.
Its atom size is bigger than Chlorine but smaller than Iodine
Elements atomic radii increase in size as they run down the columns of the periodic table or across the periodic table from right to left. So, Al is larger than Cl. XP
