context: Uranium is an elemental and toxic heavy metal whose all naturally occurring and artificial isotopes are radioactive, mostly alpha emitters. In a batch system, it has the chemical symbol U (lat. Uranium), the sequence number 92, and the CAS number 7440-61-1. The most important isotopes are 235U and 238U, which, along with 234U, are the only isotopes found in nature. The melting point of natural uranium is 1135 ° C and its density is 19050kg / m³. The 235U isotope can be used as nuclear fuel for power generation and nuclear weapons.
