238 nucleons in 238U.
The most common isotope of uranium is uranium-238 with 146 neutrons.
146 neutrons.
there are 24 stable isotopes in the element calcium.
Nucleons are protons and neutrons; the have a mass near 1. But nucleons contain quarks and gluons. I've been trying to work backward from the question to determine what you were really trying to ask, and I think it may have been something along the lines of "does uranium have the greatest mass deficit per nucleon"? In which case the answer is no. An isotope of nickel holds that position, with two iron isotopes close behind. Uranium is not even a contender; there actually aren't many elements that don't have at least one isotope that has a higher binding energy than any uranium isotope.
The most common isotope of uranium is uranium-238. The atomic number of uranium is 92, which means it contains 92 protons. To calculate the number of neutrons, subtract the number of protons from the mass number 238. No. of neutrons in 238U = 238 - 92 = 146
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
all isotopes of uranium have 92 protons, that is what makes them uranium.
A stable isotope of uranium-235 contains 143 neutrons.
In an electrically neutral isotope, the number of protons equals the atomic number, which is 56 in this case. The atomic mass of 130 represents the total number of nucleons, which includes both protons and neutrons. Therefore, the number of nucleons in this isotope is 130.
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
Uranium-238 has 146 neutrons.
92
