A radioactive transuranic element, it was discovered by bombarding curium with alpha particles (helium ions). Since the lanthanide homologue of californium ( dysprosium) . A coming- of-age crossover novel about growing up, selling out, and fitting in. The first cube of the element had sides nanometers long. A human hair is 80nanometers thick.
The method used to make californium involved bombarding curium-2with alpha particles (helium-nuclei) using the cyclotron. The periodic table is a chart that shows how chemical elements are related to each other. Uranium is element number in the periodic table, so elements with atomic numbers greater than are said to be transuranium elements.
