Actinides

List of isotopes

Californium is a radioactive chemical element with the symbol Cf and atomic number 98. It is an actinide element, the sixth transuranium element to be synthesized, and has the second-highest atomic mass of all the elements that have been produced in amounts large enough to see with the unaided eye (after einsteinium).

Density @ 20oC: 13.67 g/cm3. Show more, including: Heats, Energies, Oxidation, Reactions, Atomic volume: 18.4 cm3/mol.

Californium is another radioactive element, used primarily in research and in instruments employed in the petroleum industry. A gram of californium-252 can cost $27 million per gram, which makes it considerably more expensive than lutetium, but less than francium.

Even though gold carries power in terms of inflation and general value, diamonds can often have a higher resale price. But again, it all depends on the diamond characteristics.

Are diamonds a good investment? On paper, diamonds make great investment sense. They have high intrinsic value, they’re always in demand and they last forever – plus, they’re small, portable and easy to store (unlike that priceless Ming vase you just had to have at auction).

The number ‘916’ is actually used to denote the purity of gold in the final product, which means 91.6 grams of pure gold in 100 gram of alloy. The figure 916 is thus 22 carat by 24 carat (22/24). Similarly, 958 gold is 23 carats (23/24) and 750 gold is 18 carats (18/24).

Purity: 24K signifies 99.9 % purity and 22K is approximately 91 percent pure gold, with the other 9% consisting of other metals such as copper, silver,zinc, etc….How can I measure gold purity using karats?

However, non-hallmarked gold ornaments are still referred as ”KDM gold”. That means, the major difference between the two- BIS 916 gold and KDM gold is that the BIS 916 gold provides guarantee on purity and fineness of gold jewellery as it’s certified.

916 and 920 gold is the same as 22K Gold.

The current 22k gold price per gram is $52.44….All Karats Per Todays Prices USD (gram)
