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

How many protons neutrons and electrons does ion have?

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.

How many protrons and neutrons are in iodine?

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.

How many neutrons are there in iodine?

Number of neutrons = Mass number - Number of protons = 127 - 53 = 74


Why do you think iodine-126 is called iodine-126?

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.
