How many neutrons are present in iodine 126?
How many neutrons does an iodine-131 atom have? Iodine-131 is an isotope of the normal atomic iodine, element number 53. The stable normal atom, which is iodine127, has 53 protons and 74 neutrons (atomic weight 53 + 74 = 127).
How do you find the neutrons of iodine?
The symbol used here indicates the atomic number (number of protons) is 53. This fact is redundant because the letter I indicates the element is iodine and iodine has 53 protons. The mass number (number of protons plus neutrons) is 131. By deduction, has: 131-53=78 neutrons.
How many neutrons are in iodine 133?
the ion with a 1+ charge, atomic number 55, and mass number 133. the ion with 54 electrons, 53 protons, and 74 neutrons.

How many neutrons are in iodine 131?
78 neutrons
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). With “too many” neutrons in its nucleus, it is unstable and radioactive, with a half-life of eight days.
How many number of protons and electrons in iodine?
Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure. 53 electrons (unless it is an Ion) 77 neutrons. Allright Iodine has- 53 protons. The proton number is the atomic number of the Similarly, through gaining an electron, iodine becomes negatively charged.
What element has 6 protons 6 neutrons and 6 electrons?
Carbon-12; one of 5 elements in the human DNA is composed of 6 protons, 6 electrons and 6 neutrons, which equates to 666. Carbon-12 is the most abundant of the two stable isotopes of the element carbon, accounting for 98.89% of carbon.
How do you determine the number of neutrons in an atom?
To find the number of neutrons in an atom of the isotope, simply subtract the number of protons (atomic number). So, carbon-13 has 7 neutrons, because carbon has atomic number 6.
How many neutrons are in each isotope?
Uranium-235 and uranium-238 are isotopes of uranium. Each uranium atom has 92 atoms (which you can verify using a periodic table), so these isotopes contain 143 and 146 neutrons, respectively.
