Uranium 234.

Den smältpunkt av aktinider har inte en klar beroende på antalet f -electrons. Uranium-234 (234 U, U-234) is an isotope of uranium.In natural uranium and in uranium ore, 234 U occurs as an indirect decay product of uranium-238, but it makes up only 0.0055% (55 parts per million) of the raw uranium because its half-life of just 245,500 years is only about 1/18,000 as long as that of 238 U. Natural isotopes of uranium: 234U, 235U, 238U. Isotopes: atoms of the same element having identical number of protons and electrons but a different nunmber of neutrons. Uranium-234.
