As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium , iridium and palladium by mass and iridium, gold and platinum by volume . Carbon in the form of diamond can be more expensive than rhodium.
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.
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]
Few compounds of californium have been made and studied. [1] The only californium ion that is stable in aqueous solutions is the californium(III) cation. [2] The other two oxidation states are IV (strong oxidizing agents) and II (strong reducing agents). [3]
