Uranium 235 has 92 protons and 92 electrons.
To find the number of neutrons, follow this equation:
Mass # - Atomic # = # of neutrons.
Since the mass number of uranium 235 is 235 and has an atomic number of 92, the number of neutrons is 143.

∙ 13y agoThe number 235 is called the mass number and is equal to the number of protons plus the number of neutrons. Therefore if you subtract the atomic number (which is the number of protons and is the number listed on the Periodic Table) from the mass number you will be left with the number of neutrons.
SO
235-92=143 neutrons

∙ 14y agoYou can find the number of neutrons by looking up the atomic number (number of protons) on the periodic table and subtracting it from the Atomic Mass number. Number of neutrons = (atomic mass number) - (atomic number). Since Uranium's atomic number is 92, Uranium-238 contains 146 neutrons.

Uranium has the atomic number of 92 (the number of protons).
The atomic mass of Uranium-235 is 235, the total of 235 protons and neutrons in the nucleus.
Subtracting the number of protons gives the neutron count for the isotope. 235 -92 = 143

How many neutrons does an mg2 ion have?
It has 12 neutrons.
What is being done to reverse nuclear power?
You can't reassemble the U235 nucleus after it has fissioned, so you can't put nuclear power into reverse.
How many neutrons are found in argon?
There are 18, 20 or 22 neutrons.
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
How many protons and neutrons does the nucleus of argon?
18 protons and 18, 20 or 22 neutrons.
How many neutrons are in Element 92?
Element number 92 is Uranium and there are two main isotopes - U235 and U238. In U235 there are 92 protons so there are 235 - 92 = 143 neutrons. In U238 there are thus 146 neutrons
Why is large mass of uranium-235 needed for a chain reaction?
Each time a U235 atom decays, it emits 2-3 neutrons. The likelihood that one of these neutrons is captured by another U235 atom INCREASES with more mass. The SHAPE of this mass will also play a role, imagine a thin wire of U235, compared to a sphere, with regards to how likely a chain reaction will occur. Neutron reflection can also help redirect an errant neutron back into the mass so it can react instead. Compression (increase of density) plays a role as well.
Isotopes of elements?
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
What do you use to split a uranium nucleus in nuclear fission?
Fast neutrons fro U238 but you can use slower neutrons for U235. Other fast bombardment nucleii may also be used
What can isotopes of the same elements have a different number of what?
Neutrons in the nucleus of the element's atoms. It is the number of protons in the nucleus that determines what the element is. It is the total of neutrons and protons in the nucleus that gives the isotope number. Uranium generally comes in two isotopes, U235 and U238. All uranium is radioactive -- that is, it will decay into other elements over time. U238 is much more common and is very long lived radioactively and is not explosive and cannot be made into atomic bombs. U235 is much rarer, but is highly radioactive and can be made into atomic bombs. The two isotopes are mixed together at the atomic level. This is what Iran is trying to do now in it's efforts to concentrate enough U235 to make a bomb -- the process is called "enrichment."
