Plutonium: Understanding Its Properties and Characteristics

What comes to mind when you hear the word Plutonium? Perhaps you think of nuclear weapons, the risk of radiation, or maybe you don’t have any idea at all.

Either way, this article aims to educate and inform readers about the properties and characteristics of Plutonium, along with its discovery, identification, location on the periodic table, uses, toxic effects, and some interesting facts.

Properties and Characteristics of Plutonium

Plutonium is a radioactive element with the chemical symbol Pu and the atomic number 94. It is produced by nuclear reactors and can be found naturally in uranium ores.

There are fifteen isotopes of plutonium, and all are unstable, meaning they decay and emit alpha particles. The most commonly used isotopes are plutonium-238 and plutonium-239.

Plutonium-238 undergoes alpha decay and has a half-life of 87.7 years. On the other hand, plutonium-239 undergoes alpha decay and has a half-life of 24,100 years.

This long half-life makes plutonium-239 useful in nuclear fission processes. It produces a large amount of energy when split into two smaller nuclei, like uranium and other fissionable elements.

Discovery and Identification of Plutonium

Plutonium was first discovered in 1940 when scientists were studying uranium. Glenn T. Seaborg and his team of scientists bombarded uranium-238 with alpha particles, causing it to undergo a series of nuclear reactions. They identified the new element using a cyclotron and named it after the dwarf planet, Pluto.

The atomic mass of plutonium is 244. It has a configuration of [Rn] 5f6 7s2 and seven valence electrons.

It is a silvery-gray metal that is malleable and ductile. Plutonium is also a poor conductor of heat and electricity and highly radioactive.

Location on the Periodic Table

Plutonium belongs to the actinide series or the rows below the periodic table. It comes after uranium and before americium.

Actinide series elements are characterized by the increasing number of electrons in the f-orbitals of their atoms as we move from left to right.

Uses of Plutonium

Plutonium has various uses, including military applications, space probes, scientific studies, and in nuclear reactors. During the Cold War, the United States used Plutonium to make atomic bombs.

The element is highly dense and can be used as a power source for space probes because it can sustain high radiation levels. Plutonium is also used in scientific experiments, especially those studying nuclear energy.

Toxic Effects of Plutonium

Plutonium is a dangerous and toxic heavy metal that can lead to serious health problems and radiation sickness. When exposed to radiation, the human body can absorb and store plutonium, which can cause cancer, genetic mutations, and birth defects.

Inhaling plutonium can cause lung cancer. As such, strict safety measures must be taken when handling plutonium.

Interesting Facts about Plutonium

Plutonium is known for its unique behaviors when exposed to air and heat. While other metals rust, Plutonium corrodes rapidly and can catch fire spontaneously when exposed to air.

This is due to the reaction of the metal with moisture. It is also interesting to note that Plutonium is the only synthetic element to occur naturally.

Trace amounts of Plutonium have been detected in natural deposits of uranium. Its discovery and subsequent use in making atomic bombs were pivotal events in world history.


In summary, Plutonium is a radioactive, heavy metal element that has various uses in military, scientific, and space applications. It is highly dangerous and toxic, causing serious health problems when contaminated.

Its unique properties, behaviors, and discovery make it an interesting and important element in human history. Understanding the properties and characteristics of Plutonium helps us to appreciate the element’s potential and dangers.

It is important to handle the element with great care and respect its potential for destruction.

Plutonium Toxicity and Interesting Facts

Plutonium is a synthetic element that has been subjected to rigorous safety procedures from its discovery. In addition to its radioactive properties, plutonium is also highly toxic and hazardous if improperly handled.

This article will delve into the toxicity of plutonium, including prolonged inhalation effects, health risks, and some interesting facts.

Prolonged Inhalation Effects

One of the most significant risks posed by plutonium is through inhalation. The inhalation of plutonium dust or vapors can cause serious health problems.

When plutonium enters the lungs, it can adhere to the tissue and release alpha particles that damage cells. The alpha particles’ energy is highly concentrated and can be absorbed by nearby tissues, causing burns, inflammation, and, in severe cases, cancer.

The prolonged inhalation of plutonium dust can lead to lung cancer, liver cancer, and bone sarcoma. Studies on animals have shown that inhaling plutonium can also lead to the accumulation of the element in various organs resulting in localized radioactivity.

Health Risks

The health risks of plutonium exposure have been well documented. Plutonium is a lethal poison that can cause radiation sickness, genetic mutations, and birth defects when ingested or inhaled.

Plutonium’s radioactive properties make it a dangerous substance, as it can cause serious harm even in small amounts. The long-term health effects of plutonium exposure can be fatal, as the complete elimination of plutonium from the body is difficult.

Accumulation in the body is one of the primary health risks of plutonium exposure. Due to its chemical properties, plutonium can accumulate in the bones, liver, and other organs, causing cell damage and potentially leading to cancer.

Any exposure-related illness stemming from plutonium inhalation or ingestion is usually latent, taking months or years to reveal themselves. Severe cases of plutonium poisoning can result in liver, heart, and kidney failure, all of which can be fatal.

Interesting Facts

Plutonium’s unique properties are a source of curiosity and intrigue for many. One of its unique properties is its liquid behavior.

Plutonium expands when heated, becoming the only metal to become more massive when molten. At room temperature, it is produced as a solid metal, with a bright silver-gray sheen.

Another interesting fact about plutonium is that it is known to glow in the dark when exposed to air. This is due to the metal’s high reactivity with oxygen, creating a halo of alpha particles that interact with air molecules, resulting in an ethereal glow.

Lastly, plaguing the legacy of plutonium is its destructive historical significance. Plutonium was used in atomic bombs during World War 2, with the United States dropping the first plutonium bomb, codenamed Trinity, on the Alamogordo, New Mexico desert on July 16, 1945.

This catastrophic event sealed plutonium’s connection with war and its potential for destruction of life and ecosystems alike.


In conclusion, the properties of plutonium are fascinating, and its uses have benefitted scientific, military, and energy sectors alike. However, its potential for toxicity poses a considerable danger to human health and the environment.

The long-term health effects of plutonium exposure are unavoidable, making safety procedures critical in handling and storing this element. Plutonium’s historical significance is also not lost in its rise to prominence in the technological advancement of man.

Nevertheless, it marks a testament to the heights human innovation can attain in evolving with technology and the problems requiring solutions.
