Thaum Henri Becquerel tshawb xyuas qhov kev tshawb pom tshiab X-rays xyoo 1896, nws tau coj mus rau kev tshawb fawb txog seb uranium ntsev cuam tshuam los ntawm lub teeb. Los ntawm kev huam yuaj, nws pom tias uranium ntsev spontaneously emit ib tug nkag mus rau hauv hluav taws xob hluav taws xob uas yuav tsum tau sau npe rau ntawm daim duab duab.
Becquerel nrhiav tau dab tsi txog lub atom?
Zoo li Thomson qhov kev tshawb pom ntawm electron, qhov kev tshawb pom ntawm radioactivity hauvuranium los ntawm Fabkis tus kws kho mob Henri Becquerel hauv xyoo 1896 yuam cov kws tshawb fawb kom hloov pauv lawv lub tswv yim txog cov qauv atomic. Radioactivity qhia tau hais tias lub atom tsis yog indivisible los yog hloov tsis tau.
Becquerel paub dab tsi?
Henri Becquerel, nyob rau hauv tag nrho Antoine-Henri Becquerel, (yug Lub Kaum Ob Hlis 15, 1852, Paris, Fabkis-tuag Lub Yim Hli 25, 1908, Le Croisic), tus kws kho mob Fab Kis uas nrhiav tau xov tooj cua los ntawm nws qhov kev tshawb nrhiav ntawm uranium thiab lwm yam tshuajNyob rau hauv 1903 nws tau muab lub Nobel nqi zog rau Physics nrog Pierre thiab Marie Curie.
Henri nrhiav tau xov tooj cua li cas?
Xyoo 1901 Becquerel tau tshawb pom tias cov xov tooj cua tuaj yeem siv rau tshuaj. Henri tau ua qhov kev tshawb pom no thaum nws tso ib daim ntawm radium hauv nws lub hnab tsho khuam thiab pom tias nws tau raug hlawv los ntawm nwsQhov kev tshawb pom no tau ua rau muaj kev kho hluav taws xob uas tam sim no siv los kho mob qog noj ntshav.
Leej twg nrhiav tau hluav taws xob nuclear?
Txawm hais tias nws yog Henri Becquerel uas nrhiav tau qhov tshwm sim, nws yog nws tus kws kho mob tub ntxhais kawm, Marie Curie, uas tau hu nws: xov tooj cua. Nws yuav mus ua haujlwm pioneering ntau ntxiv nrog cov ntaub ntawv xov tooj cua, suav nrog kev tshawb pom cov xov tooj cua ntxiv: thorium, polonium, thiab radium.
