Lower ranks of coal can be less expensive, for example sub-bituminous coal can cost around US$0.038/kg carbon. [19] Graphite flakes can cost around US$0.9/kg carbon. [ 20 ] Price of synthetic industrial diamond for grinding and polishing can range from 1200 to 13 300 USD/kg, while cost per weight of large synthetic diamonds for industrial ...
Francium-223 is the most stable isotope, with a half-life of 21.8 minutes, [8] and it is highly unlikely that an isotope of francium with a longer half-life will ever be discovered or synthesized. [22] Francium-223 is a fifth product of the uranium-235 decay series as a daughter isotope of actinium-227; thorium-227 is the more common daughter. [23]
So why is orange juice so expensive right now? Gassing up. A favorite talking point among Republican lawmakers is noting how gas prices under the Biden administration are much higher than under ...
The abundance of the chemical elements is a measure of the occurrences of the chemical elements relative to all other elements in a given environment. Abundance is measured in one of three ways: by mass fraction (in commercial contexts often called weight fraction), by mole fraction (fraction of atoms by numerical count, or sometimes fraction of molecules in gases), or by volume fraction.

I'm making a fairly major edit to the history section based off a web site and paper I found. As of right now, I'm not done adding the info yet, so don't bother commenting on it *grin*. I do, however, need to find why/how alkalinium was refuted. --Cryptic C62 · Talk 02:48, 9 April 2007 (UTC) Regarding the number of isotopes.
So why is orange juice so expensive right now? Janna Herron. September 14, 2024 at 4:42 AM. The price of frozen orange juice is skyrocketing — and no, Clarence Beeks and the Dukes are not involved.
Why is francium so unstable? The article doesn't explain. Google found me a Prezi presentation (), but first off that's not a reliable source for expanding the francium article, and secondly it doesn't explain why many isotopes of related elements, e.g. 238 U with 54 more neutrons than protons, are so much longer lived.
