Uranium-238 (238 U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor.

It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found. Other isotopes such as uranium-233 have been produced in breeder reactors. In addition to isotopes found in nature or nuclear reactors, many isotopes with far shorter half-lives have been produced, ranging from Shop for Pantone® 2347 U samples and products on Pantone.

92p 142n electrons: same number as protons, except in ions. Source(s): Chart at bottom: http://en.wikipedia.org/wiki/Isotopes_of_aluminium Also 2010-04-05 · You can find that on a periodic table by looking up uranium. To find the neutrons subtract the protons from the 234, 235, and 238. So, for Uranium-234, there are 234-92=142 neutrons.
