umlium

Umlium is a chemical element with the symbol Um and atomic number 101. It is a synthetic element that was first produced in 1967 by a team of scientists led by Albert Ghiorso at the Lawrence Berkeley National Laboratory in the United States. Umlium is named after the University of California, Berkeley, where the element was discovered.

Umlium is a transuranic element, meaning it is located in the periodic table beyond uranium. It is a radioactive element with a half-life of approximately 15.7 minutes. The most stable isotope of umlium is Um-243, which has a half-life of about 4.5 hours.

Umlium is primarily used for scientific research purposes. Its properties and behavior are studied to better understand the behavior of heavier elements and the limits of the periodic table. Due to its short half-life and the difficulty of producing it, umlium is not used in any practical applications.

The production of umlium involves bombarding a target of neptunium-237 with carbon-12 ions in a particle accelerator. This process results in the formation of umlium-243, which then decays into other elements. The production of umlium is a complex and expensive process, and only small amounts of the element have been produced to date.
