To find out how many neutrons are in any element, you must take the Atomic Mass of the element and subtract the atomic number/ the number of protons.
# of neutrons = atomic mass - # of protons
This is because the atomic mass of an element is the number of protons added to the number of neutrons. The atomic mass is measured in atomic mass units, where one proton has a mass of 1 amu and one neutron has a mass of 1 amu. Elements also have electrons, however their mass is negligible, which means that it can be ignored because it is minor.
In the case of iodine, it's atomic mass is approximately 127 (126.9). It's atomic number, which is also the number of protons and the number of electrons, is 53. Thus, the number of neutrons is:
127 - 53 = 74
This question is incomplete. One cannot say how many neutrons an atom of iodine has unless one also specifies which isotope of iodine one is referring to. Since the atomic number of iodine is 53, that means that there are 53 electrons and 53 protons in the neutral atom.
Tungsten has 74 protons and 74 electrons, but it has 110 neutrons. Tantalum has 108 neutrons, but 73 protons and 73 neutrons.
Iodine has 53 protons. Iodine 127 has 74 neutrons. With a negative charge, it would have an extra electron, meaning it would have 54 electrons.
The atomic number of iodine is 53. So there are 53 protons and 53 electrons. For I-135 isotope, there are 82 neutrons (135 - 53 = 82)
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.
The mass number for iodine is 131, which is the sum of the protons and neutrons. Iodine has 53 protons and 53 electrons, if neutral. To find how many neutrons iodine has subtract 53, the number of protons from the mass number of 131. This shows that iodine has 78 neutrons.

A typical atom of iodine contains 74 neutrons.
53
you can find the number of protons by looking at the atomic number (53), as the number of protons does not change between isotopes. You can find the number of neutrons by subtracting the atomic number from the Atomic Mass (131), therefore, iodine-131 has 53 protons and 78 neutrons.
The isotope iodine-122 has 53 protons and electrons and 69 neutrons.

Iodine (I) has 53 protons and 74 neutrons.
Neutrons in iodine: 74.
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
Iodine has 53 protons. Iodine 126 has 126 - 53 = 74 neutrons. So iodine 126 is called iodine 16 because it has 53 protons and 74 neutrons. There are other types of iodine, called neuclides of iodine, which have different numbers of neutrons. All of them have 53 protons. So iodine 141 has 53 protons and 141 - 53 = 88 neutrons.
