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.
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.
Fluorine has the smallest atomic radius among fluorine, chlorine, bromine, iodine, and astatine.
Smaller
Iodine is the biggest atom among bromine, fluorine, chlorine and iodine as it has the highest atomic number and atomic radius.
The empirically measured covalent radius of tin is 145 pm; for iodine this radius is 140 pm.
Iodine is a bigger atom than chlorine because it has more electrons and atomic radius.
The atomic radius of an atom generally increases as you move down a group in the periodic table due to the addition of more electron shells. Iodine is located below fluorine in the same group (Group 17), so iodine has more electron shells compared to fluorine, leading to a larger atomic radius.
varys from 2,342 kilometres to 103,230 kilometres in diameter
Atomic size increases down a group as the energy level (or shell) increases. So Astatine will have the largest size (radius) in group 17
Strontium has a larger atomic radius than iodine. This is because strontium is located in Group 2 of the periodic table and is a metal, while iodine is a nonmetal found in Group 17. As you move down the periodic table, the atomic radius increases due to the addition of electron shells, and strontium, being lower in the table, has more electron shells than iodine.
The Halide family contains elements with an atomic number of 53, which corresponds to the element iodine. Iodine is a nonmetal that typically forms negatively charged ions, or halides, when it reacts with other elements. It is an essential nutrient for humans and is commonly used in various applications, including photography and medicine.
