The element uranium (U) has 92 protons in its nucleus. That's where its atomic number comes from. When we see an isotope of an element written in "standard" form, the element name or symbol will be followed by the Atomic Mass (atomic weight) of the isotope. This number is basically the number of protons and neutrons (called nucleons when they are in an atomic nucleus) in an atom. In this case, we have U-235 and U-238. In the first case, 235 - 92 = 143, so U-235 has 143 neutrons. In the second case, 238 - 92 = 146, so U-238 has 146 neutrons. See the Related Questions below for how to find the number of neutrons in any atom.

How many neutrons are in the nucleus of a Chlorine atom?
A Chlorine atom typically has 18 neutrons in its nucleus. This is because the atomic number of Chlorine is 17, which represents the number of protons in its nucleus. By adding the number of protons to the number of neutrons, we can determine the total number of particles in the nucleus.
How many protons electron and neutrons does Boron have?
Boron (symbol B, atom number 5) is build up with:5 protons, 5 electrons and 5 or 6 neutrons, depending on the mass number of the two possible isotopes: B-(10) has 5 neutrons and B-(11) has 6 of them respectively.
How many protons electrons and neutrons respectively does iodine have?
The mass number for iodine is 131, which is the sum of the protons and neutrons. Iodine has 53 protons and 53 electrons, if neutral. To find how many neutrons iodine has subtract 53, the number of protons from the mass number of 131. This shows that iodine has 78 neutrons.
