Plutonium is a chemical element with the atomic number 94 and the symbol Pu. It is a radioactive, metallic, and silvery-gray element that is highly toxic and dangerous to handle. Plutonium is a member of the actinide series of elements and is located in the seventh period of the periodic table.

Plutonium is a synthetic element, which means that it does not occur naturally on Earth. It was first produced in 1941 by scientists Glenn T. Seaborg, Joseph W. Kennedy, Edwin M. McMillan, and Arthur C. Wohl at the University of California, Berkeley. They created it by bombarding a sample of uranium-238 with neutrons in a nuclear reactor.

Plutonium is one of the most abundant elements on Earth, but it is not found in its pure form in nature. It is produced in nuclear reactors and can be extracted from spent nuclear fuel rods. It is also produced as a byproduct of nuclear weapons testing.

Plutonium has several isotopes, which are versions of the element with the same number of protons in their atomic nuclei, but a different number of neutrons. The most stable isotope of plutonium is Pu-239, which has a half-life of 24,100 years. This means that half of the atoms in a sample of Pu-239 will decay (or transform into another element) over a period of 24,100 years.

Plutonium has several uses, including in nuclear weapons, nuclear power plants, and space exploration. It is used as a fuel in nuclear reactors to produce electricity, and it is also used in the production of nuclear weapons. Plutonium is also used in the production of medical isotopes, which are used to diagnose and treat certain medical conditions.

Plutonium is highly toxic and poses a significant health risk to humans. It can cause cancer and other serious health problems if ingested or inhaled. It is also a potent alpha emitter, which means that it can cause cell damage and death if it comes into contact with living tissue.

Plutonium is classified as a hazardous material and must be handled with extreme caution. It is usually stored in secure facilities, such as nuclear power plants or research labs, to prevent accidents or theft.

Now that you know more about plutonium, test your knowledge with the following quiz:
