All the chemical elements contain protons, neutrons and electrons.
Uranium
Now only Namibia, Niger and South Africa are important producers of uranium.
all isotopes of uranium have 92 protons, that is what makes them uranium.
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.
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.

Uranium
its a thing in the world that makes up other things. A few are iron and argon and also my favorite is Uranium.
Uranium 235
We're what makes the world churn.
Kazakhstan (in 2010).
There are 3 major isotopes of uranium: Uranium-238, 235, and 234. These numbers are the amount of neutrons in the nucleus. Since Uranium only has 92 protons, this makes these isotopes VERY neutron-heavy!Uranium-238 is the most common in nature, followed by 235, then 234. All these are radioactive isotopes. Because there are so many neutrons in Uranium, it makes it fissile -- easy to split.
