When uranium-235 is added to natural uranium, it increases the overall percentage of uranium-235 in the mixture. This can make the uranium more suitable for use in nuclear reactors or weapons, as uranium-235 is more fissile (more easily split by neutrons) than uranium-238.
The chemical symbol of uranium is U.
Uranium-235 is the element with a mass number of 235. It is a radioactive isotope of uranium that is used in nuclear reactors and nuclear weapons.
Uranium-235 and uranium-238 are not considered molecules, they are isotopes of uranium. Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. Both uranium-235 and uranium-238 are radioactive isotopes, meaning they spontaneously decay and emit radiation.
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 an isotope of uranium making up about 0.72% of natural uranium.
Approx. 0,7 % uranium 235 in natural uranium.

The atomic number of uranium is 92. Uranium-235 has 143 neutrons.
Uranium 235 (and also all the isotopes of uranium) has 92 electrons.

Uranium-235 and uranium-238 are not considered molecules, they are isotopes of uranium. Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. Both uranium-235 and uranium-238 are radioactive isotopes, meaning they spontaneously decay and emit radiation.
Uranium is a chemical element with three natural isotopes (234, 235, 238). The natural uranium has cca. 0,72 % uranium-235; uranium with a concentration of uranium-235 under 0,72 % is called depleted uranium; uranium with a concentration of uranium -235 above 0,72 % is called enriched uranium. Uranium in nuclear power and research reactors is used as metal, aloys, uranium dioxide, uranium carbides, uranium silicides, etc.
The U-235 content in depleted uranium (DU) is typically less than 0.3%, which is much lower than the concentration found in natural uranium. DU is the byproduct of the uranium enrichment process, where the concentration of the U-235 isotope has been reduced.
