Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). In their most stable forms, Uranium has an atomic mass of 238 and plutonium has an atomic mass of 244, plutonium has a greater mass than that of Uranium. A small quantity of 7 kgs of U-235 is sufficient to create an atom bomb. The chemical symbol for Uranium is U. The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element. It was used in preparation of the atom bomb called “little boy” that was dropped in the Japanese city of Hiroshima in the World War II. All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission. to Ar(U) = 238.0289(1). E.g. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. The other category with body-centered cubic structure is known as γ variant of uranium allotrope which is stable beyond 775 °C. German chemist Martin-Heinrich Klaproth discovered the element in 1789, following William Hershel's discovery of the planet in 1781. It is ductile, malleable, and capable of taking a high polish. It is an important nuclear fuel. very gradually in geological time because of its faster decay.

Thorium, Protactinium, Neptunium, Plutonium, Americium, Curium, Berkelium, Californium, Einsteinium, Fermium, Mendelevium, Nobelium and Lawrencium are the elements in the same group. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. justified a more precise value for the standard atomic weight, thus leading 234U, itself a decay product of 238U, is in equilibrium At room temperature and pressure, it is a solid metal.
