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

What element has 53 protons and 74 neutrons?
Tungsten has 74 protons and 74 electrons, but it has 110 neutrons. Tantalum has 108 neutrons, but 73 protons and 73 neutrons.
How many protons electrons and neutrons does iodine have?
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.
How many protons neutrons and electrons does iodine-135 have?
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)
How many neutrons are in iodine-127.?
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.
How many protons neutrons and electron respectively does 127 Iodine with negative charge?
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.
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 protons electrons and neutrons respectively does iodine 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 neutrons does iodine cost?
Iodine typically has an atomic number of 53, which means it has 53 protons. The most common isotope of iodine, iodine-127, has 74 neutrons. To find the number of neutrons in an isotope, you subtract the atomic number from the mass number; for iodine-127, that calculation is 127 (mass number) - 53 (atomic number) = 74 neutrons.
How many neutrons are in an atom of I?
A typical atom of iodine contains 74 neutrons.
How many neutrons are Iodine?
53
How many neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
How many protons neutrons and electrons does iodine-122 have?
The isotope iodine-122 has 53 protons and electrons and 69 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 and protrons are in iodine-131?
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 in an atom I?
A typical atom of iodine contains 74 neutrons.
How many protons and neutrons are found in the iodine 129 atom?
It's 53, because the number of protons equal the element's atomic number. You can easily find it on a periodic table.
What element has 53 protons and 74 neutrons?
Tungsten has 74 protons and 74 electrons, but it has 110 neutrons. Tantalum has 108 neutrons, but 73 protons and 73 neutrons.
