Alpha hais muaj ib hluav taws xob vim cov protons. Thaum lawv txav mus los ntawm qhov teeb meem, lawv pheej cuam tshuam nrog lwm tus them cov khoom , xws li electrons. Cov txheej txheem no hloov cov lus tsa suab (lub zog) ntawm lub alpha particle rau cov electrons, yeej khob lub electrons dawb nyob rau hauv tus txheej txheem.
Kuj paub yog, dab tsi yog tus nqi ntawm alpha particle?
Ib qho alpha particle yog ib pob ntawv txav ceev uas muaj ob protons thiab ob neutrons (ib tug helium nucleus). Alpha hais txog tus nqi ntawm +2 thiab cuam tshuam nrog cov teeb meem. Ua thaum lub sij hawm 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.
Tsis tas li ntawd, dab tsi yog qhov khoom siv hluav taws xob? Hauv physics, a nqi particle yog a particle nrog ib hluav taws xob . Nws tuaj yeem yog electron lossis proton, lossis lwm yam theem pib particle , uas yog txhua tus ntseeg tias muaj tib yam nqi (tshwj tsis yog antimatter). Lwm tus nqi particle tej zaum yuav yog ib qho atomic nucleus tsis muaj electrons, xws li alpha particle.
Ntxiv mus, puas yog alpha hais tsis zoo?
Cov alpha particle yog helium nucleus; nws muaj ob protons thiab ob neutrons. Nws tsis muaj electrons los sib npaug ntawm ob qhov zoo raug nqi protons. Alpha hais yog li ntawd zoo them cov khoom txav ntawm kev kub ceev. Beta hais yog tsis zoo nqi.
Yuav ua li cas tshwm sim thaum ib qho alpha particle raug tso tawm?
Alpha lwj tshwm sim thaum lub nucleus tsis ruaj khov vim nws muaj ntau protons. Lub nucleus tawm ib alpha particle thiab lub zog. Ib alpha particle Nws muaj ob lub protons thiab ob lub neutrons, uas yog ib qho helium nucleus. Poob cov protons thiab neutrons ua rau lub nucleus ruaj khov.
