Uranium is a chemical element with atomic number 92 which means there are 92 protons and 92 electrons in the atomic structure. It is ductile, malleable, and capable of taking a high polish. To determine the most abundant isotopic form of an element, compare given isotopes to the weighted average on the periodic table. In the case of uranium atoms, this changes the atomic number from 92 to 90, making them thorium atoms. It is an important nuclear fuel. That value applies to uranium as found in normal terrestrial sources, Actinium, Thorium, Protactinium, Neptunium, Plutonium, Americium, Curium, Berkelium, Californium, Einsteinium, Fermium, Mendelevium, Nobelium and Lawrencium are the elements in the same orbital. Among the primordially occurring actinide elements, uranium has the highest atomic weight. The name derives from the planet Uranus, which in Roman mythology was "Father Heaven". It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope U-235 (Uranium, atomic number Z = 92, mass number A = 235). There are several isotopes of uranium. All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission. Solve this simple math problem and enter the result. Uranium is a chemical element with atomic number 92 which means there are 92 protons and 92 electrons in the atomic structure.
