Plutonium yog cov tshuaj siv hluav taws xob muaj hluav taws xob nrog lub cim Pu thiab tus lej atomic 94. Nws yog cov hlau actinide ntawm silvery-grey tsos uas tarnishes thaum raug huab cua, thiab ua ib tug dull txheej thaum oxidized. Lub caij ib txwm muaj rau allotropes thiab plaub lub xeev oxidation.
Thaum twg thiab qhov twg tau pom plutonium?
History. Plutonium tau tsim thawj zaug hauv Kaum Ob Hlis 1940 ntawm Berkeley, California, los ntawm Glenn Seaborg, Arthur Wahl, Joseph Kennedy, thiab Edwin McMillan. Lawv tsim nws los ntawm bombarding uranium-238 nrog deuterium nuclei (alpha hais).
Thaum twg plutonium siv thawj zaug?
Plutonium yog thawj zaug tsim thiab cais tawm hauv 1940 thiab tau siv los ua "Fat Man" atomic foob pob uas tau poob rau Nagasaki thaum kawg ntawm Tsov Rog Ntiaj Teb Zaum II, tsuas yog tsib. xyoo tom qab nws tau tsim thawj zaug, hais tias Amanda Simson, tus pab xibfwb ntawm chemical engineering ntawm University of New Haven.
Vim li cas plutonium khaws cia zais cia?
Kev tshawb pom ntawm plutonium tau zais cia kom txog thaum 1946 vim yog Tsov Rog Ntiaj Teb Zaum II. Qhov twg plutonium tau txais nws lub npe? Nws tau muaj npe tom qab lub ntiaj teb dwarf Pluto (uas tau suav tias yog lub ntiaj teb tag nrho thaum lub sijhawm). Qhov no ua raws li kev lig kev cai pib thaum uranium tau muab npe tom qab lub ntiaj teb Uranus.
Plutonium thawj zaug ua li cas?
Plutonium yog thawj zaug tsim thiab cais tawm thaum xyoo 1940 thiab thaum ntxov 1941, los ntawm a deuteron bombardment ntawm uranium-238hauv 1.5-meter (60 in) cyclotron ntawm University of California, Berkeley.
