The most common isotope of zinc is the one with mass number 64; the atomic number of zinc is 30, which means each zinc nucleus contains 30 protons, and the mass number is defined as the sum of the numbers of neutrons and protons. Therefore, the number of neutrons is (64 - 30) or 34.
The most common isotope of uranium is uranium-238.
The most common isotope of uranium is uranium-238 with 146 neutrons.
Has had most of the uranium-235 (an isotope of uranium)) separated out of it.
Uranium's atomic number is 92. Thus, all isotopes of uranium have 92 protons. The most common isotope of uranium is 238U, which has 238 - 92 = 146 neutrons.
More than 99%of naturally occurring uranium is U-238. The valuable U-235 makes up less than 1% of uranium, and must be "enriched" in complicated processes.
The most common isotope of uranium is uranium-238.
The most common natural isotope is 238U: 99,2742 %.
The most common isotope of uranium is uranium-238 with 146 neutrons.
238 nucleons in 238U.
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
238 represents the most common isotope of uranium, uranium-238. It is a naturally occurring isotope found in uranium ores and makes up over 99% of natural uranium. It is not fissile, but can be converted into fissile plutonium-239 in nuclear reactors.
There is no uranium isotope with 234 neutrons. The questioner almost certainly meant the uranium isotope with 234 nucleons, which is a naturally occurring isotope U234 otherwise element 92, with 142 neutrons.In which case its half life would be 252,000 years.

The atomic mass of the most common isotope of plutonium (Pu-234) is higher than the masses of the uranium natural isotopes.
