Discovery ntawm Neutron . Nws yog qhov zoo tshaj plaws uas neutron tsis yog nrhiav pom mus txog 1932 thaum James Chadwick siv scattering cov ntaub ntawv los xam qhov loj ntawm qhov nruab nrab particle. Qhov kev ntsuam xyuas no ua raws li qhov kev sib tsoo ntawm lub taub hau elastic uas ib qho me me ntaus ib qho loj dua.

Tom qab ntawd, Chadwick tau ua pov thawj li cas ntawm cov neutron?

Rau ua pov thawj tias qhov particle yog qhov tseeb neutron , Chadwick ntsuas nws qhov hnyav. Hloov chaw nws ntsuas txhua yam hauv kev sib tsoo thiab siv cov ntaub ntawv ntawd los xam cov huab hwm coj. Rau nws qhov loj me me, Chadwick bombarded boron nrog alpha hais. Zoo li beryllium, boron emitted nruab nrab rays.

Tsis tas li ntawd, thaum twg James Chadwick nrhiav tau neutrons? Xyoo 1932

Tsis tas li ntawd, Chadwick ua li cas nws nrhiav tau?

James Chadwick tau muab txoj haujlwm los taug qab cov pov thawj ntawm Rutherford txoj hlua khi "proton-electron khub" lossis neutron. Xyoo 1930 nws yog nrhiav pom hais tias Beryllium, thaum bombarded los ntawm alpha hais, emitted ib tug heev nquag kwj ntawm hluav taws xob. Xyoo 1935, nws tau txais qhov khoom plig Nobel rau nws nrhiav tau.

James Chadwick pab txhawb rau txoj kev xav ntawm atomic li cas?

James Chadwick ua lub luag haujlwm tseem ceeb hauv kev atomic txoj kev xav , raws li nws nrhiav tau lub Neutron nyob rau hauv atoms . Neutrons nyob hauv nruab nrab ntawm ib qho atom , nyob rau hauv lub nucleus nrog rau cov protons. Lawv tsis muaj qhov zoo lossis qhov tsis zoo, tab sis pab txhawb cov atomic hnyav nrog cov nyhuv tib yam li proton.
