This is the isotope plutonium-240: 24094Pu.
The isotope plutonium-239, which is synthesized from uranium, has 94 protons (like all isotopes of plutonium) and 145 neutrons in its nucleus. Use the link below for more information on plutonium.
Protons = 92 Electrons = 92 Neutrons = 146 The number of electrons and protons in a neutral atom are each equal to the atomic number of the element (92). The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).Uranium has 92 protons, 92 electrons, and usually 147 neutrons, though another isotope has 143 neutrons.
The number of protons is equal to the number of electrons and the atomic number. The number of neutrons is different for each isotope (number of neutrons = atomic mass of the isotope [or mass number] - number of protons).
Protons = 92 Electrons = 92 Neutrons = 146 The number of electrons and protons in a neutral atom are each equal to the atomic number of the element (92). The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).
To convert Celsius to Kelvin, simply add 273.15 to the temperature in Celsius. So, -146 degrees Celsius is equivalent to 127.15 Kelvin.

146 neutrons.
Uranium-238 has 146 neutrons.
All the isotopes of plutonium has 94 protons and 94 electrons. For the number of neutrons of a specified isotope: number of neutrons = rounded atomic mass of the isotope - atomic number (or protons number) For plutonium-239: 94 protons, 94 electrons, 145 neutrons. The atomic number of plutonium is 94.
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.
Uranium, i think, its also has 92 protons and 92 electrons
You can't have that combination. Such an atom wouldn't be stable - not even for a tiny fraction of a second.The atomic mass is the sum of the atomic number (i.e., the number of protons), and the number of neutrons.
92 protons, 92 electrons.146 neutrons in U-238 isotope.
Uranium, atomic number 92, has several isotopes, and 238U is just one of them. Remember that a nucleon is one of the particles that make up the nucleus of an atom, and that means a proton or a neutron. In the case of this isotope of uranium, it has the 92 protons we'd expect for uranium, and it has 146 neutrons in its nucleus along with those protons. That's 238 necleons in the nucleus if 238U. Wikipedia has more information on uranium and on the nucleon, and links are provided.
The amount of neutrons can always be found by taking the atomic number from the mass number. Uranium has 146 neutrons. It depends on the isotope. See the link below for a list of uranium isotopes and how many neutrons are in each. You cannot tell how many neutrons it has with the given information. The most abundant isotope happens to be 238U, which has 146 neutrons.
It is the isotope 238U.
