Lub Plaub Hlis 20, 1902, Marie thiab Pierre Curie ua tiav cais cov hluav taws xob hluav taws xob radium ntsev los ntawm cov ntxhia pitchblende hauv lawv chav kuaj hauv Paris. Xyoo 1898, Cov Curies tau tshawb pom qhov muaj nyob ntawm cov ntsiab lus radium thiab polonium polonium Polonium yog cov khoom siv hluav taws xob uas muaj nyob hauv ob lub hlau alloy. Daim ntawv alpha yog tib qho piv txwv ntawm qhov yooj yim cubic crystalqauv hauv ib qho atom hauv paus ntawm STP, nrog ntug ntev ntawm 335.2 picometers; daim ntawv beta yog rhombohedral. https://en.wikipedia.org › wiki › Polonium

hauv lawv qhov kev tshawb fawb ntawm pitchblende.
Leej twg nrhiav tau cov khoom siv hluav taws xob?
Lub Peb Hlis 1, 1896: Henri Becquerel Discovers Radioactivity. Nyob rau hauv ib qho ntawm qhov zoo tshaj plaws kev tshawb nrhiav pom nyob rau hauv keeb kwm ntawm physics, nyob rau hauv ib tug overcast hnub nyob rau hauv lub peb hlis ntuj 1896, Fabkis physicist Henri Becquerel qhib ib tug tub rau khoom thiab nrhiav tau spontaneous radioactivity.
Leej twg nrhiav tau radium thiab polonium?
Marie thiab Pierre Curie thiab nrhiav pom ntawm polonium thiab radium.
Puas Marie Curie nrhiav tau radium?
Thiab Marie tau raug pov thawj: hauv 1898 Cov Curies tau tshawb pom ob lub xov tooj cua tshiab: radium (lub npe tom qab lo lus Latin rau ray) thiab polonium (npe tom qab Marie lub teb chaws, Poland).
Vim li cas Marie Curie radioactive?
Marie Curie tuag xyoo 1934 ntawm aplastic anemia (tej zaum vim muaj hluav taws xob ntau dhau los ntawm nws txoj haujlwm nrog radium). Marie's phau ntawv tseem niaj hnub no tau muab khaws cia rau hauv cov thawv ntawv txhuas hauv Fabkis, vim tias lawv kis tau cov radium, lawv muaj xov tooj cua thiab yuav nyob rau ntau xyoo tom ntej.
