Alpha particle , raug nqi zoo particle , zoo ib yam rau lub nucleus ntawm helium-4 atom, spontaneously emitted los ntawm ib co radioactive tshuaj, muaj ob protons thiab ob neutrons khi ua ke, yog li muaj ib tug loj ntawm plaub units thiab ib tug zoo nqi ntawm ob.

Thiab cov lus nug yog, dab tsi yog nyob rau hauv ib qho alpha particle?

Ib alpha particle yog ib pob ntawv txav ceev uas muaj ob lub protons thiab ob lub neutrons (ib lub helium nucleus). Alpha hais nqa tus nqi ntawm +2 thiab cuam tshuam nrog cov teeb meem. Tsim tawm thaum alpha lwj , alpha hais tuaj yeem taug kev tsuas yog ob peb ntiv tes los ntawm huab cua thiab tuaj yeem nres tau yooj yim nrog ib daim ntawv.

Ib tug kuj yuav nug, dab tsi yog ib qho alpha particle thiab nws tuaj qhov twg? Alpha hais (a) yog composite cov khoom muaj ob lub protons thiab ob lub neutrons nruj nreem khi ua ke (Daim duab 1). Lawv raug tso tawm los ntawm cov nucleus ntawm qee cov radionuclides thaum lub sij hawm ib daim ntawv ntawm radioactive decay, hu ua alpha - lwj.

Hais txog qhov no, qhov kev piav qhia zoo tshaj plaws piav qhia txog alpha particle?

Txhais ntawm alpha particle .: ib tug zoo nqi nuclear particle zoo ib yam nrog lub nucleus ntawm helium atom uas muaj ob lub protons thiab ob lub neutrons thiab raug tshem tawm ntawm kev kub ceev hauv qee yam kev hloov pauv hluav taws xob.

Koj sau li cas alpha particle?

Alpha lwj Feem ntau tsuas yog piav raws li qhov no: 1) Lub nucleus ntawm lub atom faib ua ob ntu. 2) Ib qho ntawm cov no (the alpha particle ) mus zooming tawm mus rau qhov chaw. 3) Lub nucleus sab laug muaj nws tus lej atomic txo los ntawm 2 thiab nws cov lej txo los ntawm 4 (uas yog, los ntawm 2 protons thiab 2 neutrons).
