Californium is a silvery-white actinide metal [12] with a melting point of 900 ± 30 °C (1,650 ± 50 °F) and an estimated boiling point of 1,743 K (1,470 °C; 2,680 °F). [13] The pure metal is malleable and is easily cut with a knife. Californium metal starts to vaporize above 300 °C (570 °F) when exposed to a vacuum. [14]
As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium ... Californium-252: 15.1: 0: 60.0 ...
Californium is a rare element that is man-made and not found in nature. As the name suggests, the element was first created in the University of California’s Radiation Lab in Berkeley.
[1] Transuranic elements are difficult and expensive to produce, and their prices increase rapidly with atomic number. As of 2008, the cost of weapons-grade plutonium was around $4,000/gram, [2] and californium exceeded $60,000,000/gram. [3] Einsteinium is the heaviest element that has been produced in macroscopic quantities. [4]
Californium(III) nitrate is an inorganic compound of californium and iodine with the formula Cf(NO 3) 3. [1] It can be used as a precursor to other californium ...
Massachusetts was the most expensive place for single people and families to live comfortably, the SmartAsset study found, requiring an annual income of $116,022 for singles and $301,184 for families.
