Kev loj hlob ntawm cov Atomic Theory . Xyoo 1896, Henri Bequerel tau kawm txog cov khoom fluorescent ntawm uranium ntsev thiab muab ib daim ntawm uranium ntsev rau saum lub phaj thaij duab qhwv hauv daim ntawv dub. Nws tshawb pom, raws li kev loj hlob, tias lub phaj tau nthuav tawm hauv cov duab ntawm cov qauv uranium.

Yog li ntawd, xyoo twg Henri Becquerel tau pab txhawb rau atomic txoj kev xav?

1896

Ib tug kuj nug, Henri Becquerel nrhiav tau dab tsi? Thaum twg Henri Becquerel tshawb nrhiav qhov tshiab nrhiav pom X-rays nyob rau hauv 1896, nws tau coj mus rau kev tshawb fawb txog yuav ua li cas uranium ntsev cuam tshuam los ntawm lub teeb. Los ntawm kev huam yuaj, nws nrhiav pom hais tias uranium ntsev spontaneously emit ib tug nkag mus rau hauv hluav taws xob hluav taws xob uas yuav tsum tau sau npe nyob rau hauv ib tug yees duab phaj.

Kuj kom paub, qhov kev pab cuam ntawm Henri Becquerel yog 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), Fabkis tus kws kho mob uas tshawb pom cov xov tooj cua los ntawm nws qhov kev tshawb nrhiav ntawm uranium thiab lwm yam tshuaj. Nyob rau hauv 1903 nws tau muab lub Nobel nqi zog rau Physics nrog Pierre thiab Marie Curie.

Becquerel nrhiav tau xov tooj cua li cas?
