A massa atômica do iodo-129 (I-129) pode ser encontrada em tabelas periódicas ou bancos de dados de elementos químicos, que fornecem informações sobre isótopos específicos. A massa atômica do iodo-129 é aproximadamente 128,905 u (unidades de massa atômica).
Se você quiser calcular a massa do isótopo em um laboratório, você pode usar a espectrometria de massa, um método que permite medir a massa de átomos e moléculas com alta precisão. Este método separa os isótopos com base em suas relações massa-carga, e a massa atômica pode ser obtida a partir dos dados coletados.
- Em resumo, a massa atômica do iodo-129 é encontrada em fontes confiáveis, ou pode ser medida usando métodos experimentais como a espectrometria de massa.

How many nucleons are in the atom of iodine-131?
The 131 number is the mass number: the sum of the number of protons and neutrons. Iodine has 53 protons and will have 53 electrons if its a neutral atom. To find the number of neutrons, just subtract the mass number with the number of protons 131 - 53 = 78 neutrons. See link below for periodic table.
To the nearest atomic mass unit what is the formula mass of aluminum oxide?
The formula mass of aluminum oxide (Al2O3) is approximately 102 atomic mass units.
What element Has isotopes of mass 129131132133 and 134?
The element with isotopes of mass 129, 131, 132, 133, and 134 is iodine. These isotopes include both stable and radioactive forms, with iodine-131 being particularly well-known for its medical applications in treating thyroid conditions. Iodine is essential for human health, particularly in the production of thyroid hormones.
What are two solid metal elements that scientists might use to create an element with an atomic number of 129?
To create an element with an atomic number of 129, scientists might use isotopes of solid metal elements such as bismuth (atomic number 83) and lead (atomic number 82). By bombarding these elements with neutrons or other particles in a particle accelerator, they can potentially synthesize heavier elements. However, achieving stability and creating a new element with atomic number 129 would be highly challenging due to the instability of superheavy elements.
How many moles of silver are there in 129 g of silver?
To calculate the number of moles, we need to use the molar mass of silver, which is 107.87 g/mol. Divide the given mass by the molar mass to get the number of moles. Therefore, 129 g of silver is equal to approximately 1.2 moles of silver.
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 is the isotope iodine 75?
There is no such isotope (75) known. Iodine (atom number 53, average atomic mass 127) has 53 protons and 70 up till 82 neutrons. The lowest known isotope number therefor is 123.

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.
What is the half life of iodine-129?
Iodine-129 has a half-life of 15.7 million years and is used in some medical applications. Because of its release in nuclear testing and reactor accidents, it is a potent bio-contaminant and can affect the human thyroid gland. Its human biological half-life is about 100 days (in the thyroid gland).
What is the mass number of an atom of iodine with 76 nuetrons?
The mass number of an atom is determined by the number of neutrons and protons. Since you already know the number of neutrons, you just need the number of protons, then you can add them together. I happen to know that iodine has 53 protons, so that means that the mass number is 127.It is the protons and neutrons added together so when you add 53 and 74 you get 127! Hope that helped a lot!! :):):):):):):)
How was Iodine-131 formed?
Both iodine-129 and iodine-131 are produced by the fission of uranium atoms during operation of nuclear reactors and by plutonium (or uranium) in the detonation of nuclear weapons. US EPA Link below.
What is the product of electron capture decay of xenon isotope 129xe?
Interestly, a neutron is a proton + an electron. So, when an atom captures an electron, one of its protons becomes a neutron. Now it has 1 more neutron, but 1 less proton; making the it an atom of the element with atomic number 1 less than the original atom. The total number of protons and neutrons remains the same. Xe- 129 + e-1 = I- 129

How Much Is 129 Nickels?
To find the value of 129 nickels, multiply the number of nickels by the value of each nickel, which is $0.05. Therefore, 129 nickels is equal to 129 x $0.05, which amounts to $6.45.
