The atomic number of iodine is 53, indicating the number of protons in its nucleus. The atomic mass of iodine is approximately 126.9 atomic mass units, which represents the average mass of its isotopes taking into account their abundance.
The atomic mass of iodine is about 126.9 g/mol, which is indeed less than the atomic mass of many other elements. This low atomic mass for iodine is due to its position in the periodic table and the number of protons and neutrons in its nucleus.

To find the number of neutrons in iodine, subtract the atomic number (found on the periodic table) from the atomic mass of iodine. Iodine has an atomic number of 53, and the average atomic mass is around 126.9. Therefore, the number of neutrons in iodine is approximately 74 (126.9 - 53).
The atomic mass of iodine is 126.90 atomic mass units.
Iodine is a non metal element. Atomic mass number of it is 127.
The atomic number is the same as the number of protons in the nucleus of the particle. Therefore, every atom, ion, and isotope of iodine has an atomic number of 53 (regardless of its mass number).
79; the mass number is the sum of the protons and neutrons, and the atomic number is the number of protons. So if you take the mass number (protons + neutrons) minus the atomic number (protons), you get the number of neutrons.
The atomic mass of iodine is approximately 126.9 atomic mass units.
They show that the periodic table isn't arranged on the basis of increasing atomic mass because iodine has a mass lesser than tellurium. Iodine has a mass of 126.90 and tellurium has a mass of 127.60.
Iodine is a non meta element. Atomic mass of it is 127.6.
The atomic mass of iodine is 126.90 amu, while the atomic mass of magnesium is 24.30 amu. The difference in atomic mass between iodine and magnesium is 102.60 amu.
