Refer to the Periodic Table.
Iodine has atomic Number of 53. This tells us that there are 53 protons in the nucleus.
I-127 is the Atomic Mass.
The figure is the total of all the protons and neutrons in the nucleus of the atom.
So the total number of neutrons will be 127 - 53 = 74 neutrons.
I-125 contains 73 neutrons.
To calculate the number of protons, electrons, and neutrons in an uncharged isotope, follow these rules:
Protons = atomic number
Electrons = protons = atomic number
Neutrons = atomic mass - protons
Iodine is number 53 on the periodic table, so its atomic number is 53. It has 53 protons and 53 electrons. This particular isotope of iodine is I-125. So, it has 125-53=72 neutrons.
53 protons
72 neutrons
53 electrons (if non-ionic)
Number of neutrons = Mass number - Atomic number = 129 - 53 = 76
53 protons
53 electrons
72 neutrons
Iodine has 53 electrons. I- ion is formed when one electron is added to iodine atom. So I- (or iodide ion) has 54 electrons.
Iodine-127 has 74 neutrons.
Iodine always has 53 protons.
