It is impossible to know exactly this value; probably approx. 5.109 tons. But only a very small part of this quantity is economically to extract today.
Uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. Uranium-235 is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is more abundant in nature but less useful for these purposes.
In nature, uranium is found as uranium-238 (99.284%), uranium-235 (0.711%),[4] and a very small amount of uranium-234 (0.0058%)
Uranium 238 is transformed in thorium 234 by alpha decay.
The main difference between uranium-235 and uranium-238 is their atomic masses. Uranium-235 has 235 atomic mass units (AMU) while uranium-238 has 238 AMU. This difference in mass is due to the number of neutrons in the nucleus of each isotope.
Examples for an uranium isotope:22892U, U-238, uranium-238.
Uranium-235 is found in nature at about 0.7% concentration to uranium-238.

Uranium is a metallic element and is not classified as an acid or a base. It is a radioactive element that can be found in nature as uranium-238 and uranium-235 isotopes.
No, uranium-238 has a long half-life of about 4.5 billion years. It is a naturally occurring isotope that is commonly found in nature. Shorter-lived isotopes, such as radon-222 or polonium-214, have much shorter half-lives.
Uranium-238 has 146 neutrons.
Similarities: Both uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. They are both radioactive and can undergo nuclear fission. Differences: Uranium-235 is the primary isotope used for nuclear fuel and weapons due to its higher susceptibility to fission compared to uranium-238. Uranium-238 is more abundant in nature, constituting over 99% of natural uranium, while uranium-235 is less common.

The main difference between uranium-235 and uranium-238 is their atomic masses. Uranium-235 has 235 atomic mass units (AMU) while uranium-238 has 238 AMU. This difference in mass is due to the number of neutrons in the nucleus of each isotope.
Uranium-235 is more explosive than uranium-238. This is because uranium-235 is fissile, meaning it can sustain a chain reaction of nuclear fission, which releases a large amount of energy. Uranium-238 is not fissile and requires a neutron source to undergo fission.
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
