Nyob rau hauv alpha lwj, qhia hauv daim duab 3-3, lub nucleus emits ib 4He nucleus, ib qho alpha particle. Alpha decay tshwm sim feem ntau nyob rau hauv loj nuclei uas muaj loj heev proton rau neutron piv. Ib qho alpha particle, nrog nws ob lub protons thiab ob lub neutrons, yog ib qho kev teeb tsa ruaj khov ntawm cov khoom.
Yuav ua li cas thaum lub sij hawm alpha decay nuclear equation?
Ib tug nucleus hloov mus rau hauv lub caij tshiab los ntawm emitting alpha los yog beta hais. Alpha decay (ob protons thiab ob neutrons) hloov cov lej ntawm lub caij los ntawm -4 thiab tus lej atomic los ntawm -2. … Ib qho alpha particle zoo ib yam li helium-4 nucleus.
Dab tsi tawm thaum lub sij hawm alpha lwj?
Nyob rau hauv alpha lwj, ib lub zog helium ion (alpha particle) yog ejected, tawm hauv ib tug ntxhais nucleus ntawm atomic… Lub hauv paus alpha emitters pom ntawm cov ntsiab hnyav dua bismuth (atomic naj npawb 83) thiab tseem yog cov tsis tshua muaj-lub ntiaj teb hais los ntawm neodymium (atomic tooj 60) mus rau lutetium (atomic tooj 71).
Tus txheej txheem ntawm alpha lwj yog dab tsi?
Alpha lwj yog cov txheej txheem tawg ntawm nuclear qhov twg cov nucleus tsis ruaj khov hloov mus rau lwm lub ntsiab lus los ntawm kev tua tawm cov khoom uas muaj ob lub protons thiab ob lub neutrons. Qhov ejected particle no hu ua alpha particle thiab tsuas yog helium nucleus. Alpha hais muaj ib qho loj loj thiab muaj tus nqi zoo.
Yuav ua li cas rau lub nucleus thaum lub sijhawm hluav taws xob tawg?
Ntaunuclei yog radioactive. Qhov no txhais tau tias lawv tsis ruaj khov, thiab yuav nws thiaj li lwj los ntawm emitting ib tug hais, hloov lub nucleus mus rau lwm lub nucleus, los yog mus rau hauv lub zog qis dua. Ib txoj hlua ntawm kev lwj yuav tshwm sim kom txog rau thaum lub nucleus ruaj khov mus txog.
