How many protons electrons and neutrons are in iodine-131?
Answer: Iodine has 53 protons and 53 electrons (because it has no charge the number of protons equals the number of electrons). Iodine-131 has 131 protons and neutrons. Iodine-131 has 131 minus 53 protons = 78 neutrons.
How many neutrons does 131 iodine have?
Because its nucleus has the “correct” number of neutrons, it is stable and is not radioactive. A less stable form of iodine also has 53 protons (this is what makes it behave chemically as iodine) but four extra neutrons, for a total atomic weight of 131 (53 protons and 78 neutrons).
How many electrons are in an atom with the atomic mass of 131?
How many electrons does xenon 131 have?
|Atomic mass||131. ### 29 atomic mass units|
|Number of protons||54|

How many protons neutrons and electrons are there in an atom of iodine 128?
128 Protons, 128 Neutrons, 75 Electrons. Ronald P.
How many protons does 238u have?
Natural Decay Series of Uranium-238 Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146.
What is the mass number of iodine-131?
An isotope of this would be Iodine-131, with 53 protons and 78 neutrons. This isotope has an mass number of 131. Isotopes are elements with the same number of protons but different number of neutrons. Therefore 126.904 is the average atomic mass of Iodine, and Idodine-131 is an isotope of Iodine.
How many protons does iodine 132 have?
Iodine atoms normally have fifty-three protons and seventy-four neutrons giving an atomic weight of 127. But some iodine atoms have seventy-eight neutrons making a total weight of 131 e31I or iodine-131). Others may have seventy-nine neutrons making a total weight of 132 e32! or iodine-132).
How many protons neutrons and electrons in that order are present in the anion formed by one atom 125i?
Iodine 125 (I-125) is the isotope of iodine whose nucleus consists of 53 protons and 72 neutrons. It is an electron-disrupting radioisotope in Tellure 125 (Te-125) with a half-life of 59.4 days.
How many protons neutrons and electrons does iodine 127 have?
SolutionThe atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74).
How many protons does iodine 130 have?
|Names||iodine-131, I-131, radioiodine|
How many protons and how many neutrons are in 238u?
How many protons neutrons and electrons in that order are in the 238u 5 ion?
Write the symbol for this isotope. The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons.
What element has 86 electrons 125 neutrons?
Iodine 125. Iodine 125 is the only other radioisotope of iodine used in radiotherapy. Iodine 125 (I-125) is the isotope of iodine whose nucleus consists of 53 protons and 72 neutrons. It is an electron-disrupting radioisotope in Tellure 125 (Te-125) with a half-life of 59.4 days.
