Is Promethium A Rare-Earth?
Is promethium considered a rare-earth element? Promethium (Pm) is indeed a chemical element, but it stands out within the lanthanide series of the periodic table due to a unique characteristic—it is the only rare-earth metal that cannot be naturally found on Earth. This information was confirmed on July 25, 2023.
Is Promethium A Strong Metal?
Promethium’s Strength as a Metal
Many may wonder about the strength of promethium as a metal. To clarify, promethium is not considered one of the strongest metals. This misconception may have arisen due to an inaccurate claim made on a popular television show. In the realm of metals, strength can be attributed to various factors, including purity and alloy composition. While steel is renowned for its strength and durability, it is important to note that it is an alloy, not a pure metal. In contrast, tungsten stands out as one of the strongest pure metals, boasting exceptional strength and resilience. Thus, when assessing the strength of metals, it is crucial to consider whether they are pure elements or alloys, with tungsten emerging as a prime example of a remarkably strong pure metal.

Promethium: Unveiling the Fascinating Aspects
Promethium is an intriguing element with a range of unique characteristics worth exploring. It is identified by its atomic number 61 and represented by the chemical symbol Pm. With an atomic weight of approximately 144.9127, it falls within the category of rare earth elements, specifically belonging to the lanthanide series. Promethium’s discovery is credited to the collaborative efforts of J.A. Marinsky, L.E. Glendenin, and C.D. Coryell, who first isolated it in 1945 in the United States.
Here are five interesting facts about promethium to shed more light on this element:
- Radioactive Glow: Promethium exhibits fascinating radioactive properties, emitting beta particles that can be harnessed for various applications, including nuclear batteries and luminous paint for instrument dials.
- Artificial Creation: This element does not occur naturally on Earth and is instead produced through artificial means, typically as a byproduct of nuclear reactions in nuclear reactors or as a result of uranium decay.
- Short Half-Life: Promethium isotopes have relatively short half-lives, ranging from a few years to a few months, making them valuable in temporary power sources.
- Medical Applications: Due to its radioactivity, promethium is used in radiation therapy to treat certain medical conditions, such as eye tumors and bone cancer.
- Naming Inspiration: Promethium’s name is derived from Prometheus, the figure in Greek mythology known for bringing fire to humanity, symbolizing the element’s potential as a source of energy and illumination.
These facts illuminate the intriguing nature of promethium and its significance in various scientific and practical domains.

promethium (Pm), chemical element, the only rare-earth metal of the lanthanide series of the periodic table not found in nature on Earth.Answer and Explanation: No, promethium is not the strongest metal. Although this claim was made on a popular television show, the information is inaccurate. The strongest metal alloy is steel, but the strongest metal that is not an alloy is tungsten.The regular occurrence of promethium in the earth’s crust is about 560 g due to uranium fission and about 12 g due to alpha decay of 151Eu. Promethium was also detected in the emission spectrum of the star GY Andromedae; and possibly in HD 101065 (Przybylski’s star) and HD 965.
