What is xenon mass number?
Xenon is a non metal element. Atomic mass of it is 131.
Mass number of xenon?
The mass number of xenon is 131.
If an isotope known as iodine 131 has 53 protons How many neutrons does is have A 78 B 53 C 68 or D 184?
B. 53 neutrons. The number of neutrons in an atom is calculated by subtracting the number of protons from the atomic mass of the isotope. Since Iodine-131 has an atomic mass of approximately 131, and it has 53 protons, the number of neutrons is 131 - 53 = 78.
An atom with 55 protons and 76 neutrons?
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.

If an isotope known as iodine 131 has 53 protons How many neutrons does is have A 78 B 53 C 68 or D 184?
B. 53 neutrons. The number of neutrons in an atom is calculated by subtracting the number of protons from the atomic mass of the isotope. Since Iodine-131 has an atomic mass of approximately 131, and it has 53 protons, the number of neutrons is 131 - 53 = 78.
At sample of 131 I decays to 1.0 grams in 40 days. What was the mass of the original sample?
To determine the original mass of the iodine-131 sample, we can use the radioactive decay formula, which states that the remaining mass can be calculated using the equation ( N(t) = N_0 e^{-\lambda t} ). Given that the sample decays to 1.0 grams in 40 days, and knowing the half-life of iodine-131 is approximately 8 days, we can calculate the decay constant and then find the original mass ( N_0 ). After performing the calculations, the original mass of the iodine-131 sample was approximately 5.6 grams.
What is the name and atomic symbol of an isotope with the mass number of 214 and 131 neutrons?
The proton number of this element is 214 - 131 = 83 protons Look this number up in the periodic table. You will see that the element is Bismuth.
How many neutrons in 134Xe?
is Atomic # 134 then the protons and Electrons would be 134, The Atomic Mass of Xenon s 131. So 134-131= Neutrons 3
