Nobelium-259
Nobelium-259 is a synthetic isotope of the element Nobelium, which is part of the actinide series in the periodic table. It has an atomic number of 102 and was first discovered in 1958. Nobelium-259 is known for its short half-life of about 58 minutes, making it highly unstable and challenging to study.
This isotope is produced in particle accelerators through the bombardment of curium with calcium ions. Due to its instability, Nobelium-259 does not occur naturally and is primarily used in scientific research to explore the properties of heavy elements and their interactions.
