Thaum beryllium raug foob nrog alpha - cov khoom, cov hluav taws xob nkag mus tau zoo heevuas tsis tuaj yeem deflected los ntawm hluav taws xob lossis hlau nplaum yog muab tawm.
Yuav ua li cas thaum koj foob pob beryllium nrog alpha hais?
Thaum beryllium raug ntaus los ntawm alpha hais, neutrons raug tso tawm Cov neutrons ces ntaus ib daim ntawm paraffin, uas ejected protons mus rau hauv lub ionization chamber. Los ntawm kev soj ntsuam qhov ceev ntawm cov protons, Chadwick muaj peev xwm xam qhov loj ntawm cov neutron kom zoo ib yam li cov proton.
Thaum beryllium tau tawg nrog cov khoom hnyav heev?
Thaum beryllium raug foob nrog α-particles, tsis tshua muaj nkag mus rau hluav taws xobuas tsis tuaj yeem deflected los ntawm hluav taws xob lossis hlau nplaum raug muab tawm.
Thaum beryllium raug foob nrog alpha hais ib qho hluav taws xob nkag mus rau hauv cov qauv beryllium yog dab tsi?
Thaum alpha particle bombarded nrog beryllium qauv ib tug heev nkag mus rau hluav taws xob tawm. Qhov kev tso tawm tshiab no muaj peev xwm dhau los ntawm lead dua gamma rays. Thiab lwm yam khoom tsis zoo li cov gamma rays. Qhov emission tshiab no coj zoo li qhov nruab nrab them cov khoom uas muaj huab hwm coj sib npaug rau proton.
Thaum beryllium raug foob nrog cov khoom alpha yog cov hluav taws xob nkag mus tsis tau uas tsis tuaj yeem deflected los ntawm hluav taws xob lossis hlau nplaum tau muab tawm cov no?
Thaum beryllium raug foob nrog alpha-"particles", cov hluav taws xob nkag tsis tau zoo heev uas tsis tuaj yeem deflected los ntawm hluav taws xob lossis hlau nplaum raug muab tawm. Cov no yog. (c) Neutron yog cov khoom tsis muaj nqi, yog li nws tsis deflected los ntawm hluav taws xob lossis hlau nplaum.
