Plutonium - Wikipedia Plutonium is the element with the highest atomic number known to occur in nature Trace quantities arise in natural uranium deposits when uranium-238 captures neutrons emitted by decay of other uranium-238 atoms
Plutonium | Radioactive Element, Nuclear Fuel | Britannica plutonium (Pu), radioactive chemical element of the actinoid series of the periodic table, atomic number 94 It is the most important transuranium element because of its use as fuel in certain types of nuclear reactors and as an ingredient in nuclear weapons
Plutonium - World Nuclear Association Plutonium is the principal fuel in a fast neutron reactor, and in any reactor it is progressively bred from non-fissile U-238 that comprises over 99% of natural uranium Plutonium has occurred naturally, but except for trace quantities it is not now found in the Earth's crust
Plutonium Uses: Exploring the Industrial and Military Applications . . . Plutonium is a **radioactive synthetic element** (atomic number 94) primarily used in **nuclear weapons** and **nuclear reactors** Its applications span **military, energy, and scientific research**, though its handling requires extreme caution due to **toxicity and radioactivity**
Periodic Table of Elements: Los Alamos National Laboratory Plutonium is the heaviest primordial element in existence by virtue of its most stable isotope, plutonium-244, whose half-life of about 80 million years is just long enough for the element to be found in trace quantities in nature
Plutonium - Element information, properties and uses | Periodic Table Plutonium was used in several of the first atomic bombs, and is still used in nuclear weapons The complete detonation of a kilogram of plutonium produces an explosion equivalent to over 10,000 tonnes of chemical explosive Plutonium is also a key material in the development of nuclear power
