What are three interesting facts about plutonium?
Plutonium is named for the dwarf planet Pluto. Plutonium is not a good conductor of electricity or heat, unlike some metals. The alpha form of plutonium is hard and brittle, while the delta form is soft and ductile. Plutonium occurs naturally in the Earth’s crust in uranium ores, but it is very rare.
How many isotopes does plutonium have?
There are five “common” isotopes of plutonium, Pu-238, Pu-239, Pu-240, Pu-241, and Pu-242. These are all “fissionable” – the atom’s nucleus can easily split apart if it is struck by a neutron. The different isotopes have different “half-lives” – the time it takes to lose half of its radioactivity.

How flammable is plutonium?
Flammability. Metallic plutonium is also a fire hazard, especially if the material is finely divided. It reacts chemically with oxygen and water which may result in an accumulation of plutonium hydride, a pyrophoric substance; that is, a material that will ignite in air at room temperature.
What are some fun facts about uranium?
11 Uranium Facts
- Pure uranium is a silvery-white metal.
- The atomic number of uranium is 92, meaning uranium atoms have 92 protons and usually 92 electrons.
- Because uranium is radioactive and always decaying, radium is always found with uranium ores.
- Uranium is slightly paramagnetic.
What is the most important isotope of plutonium?
Plutonium-239
Plutonium-239 is the most important isotope of plutonium, with a half-life of 24,100 years. Pu and 241Pu are fissile, meaning that the nuclei of their atoms can break apart by being bombarded by slow moving thermal neutrons, releasing energy, gamma radiation and more neutrons.
Is uranium good for the environment?
While uranium itself is not particularly dangerous, some of its decay products do pose a threat, expecially radon, which can build up in confined spaces such as basements. Uranium in air exists as dust that will fall into surface water, on plants or on soils through settling or rainfall.
Is plutonium a hazardous substance?
Radioactive materials present the greatest hazard to those parts of the body in which they are most concentrated. Plutonium is also a toxic metal, and may cause damage to the kidneys.
What are 5 interesting facts about potassium?
Fun Potassium Facts
- Potassium is a shiny, lustrous metal at room temperature.
- Potassium vigorously reacts with water to form hydrogen gas.
- Potassium was the first metal to be discovered by electrolysis.
- Potassium has a low density for a metal.
- Potassium burns with a bright red in a flame test.
