Hauv Alpha Decay lub nucleus tau muab faib ua 2 ntu nrog ib qho ntawm cov no - cov alpha particle - zooming tawm mus rau qhov chaw. Lub nucleus muaj nws tus lej atomic txo los ntawm 2 thiab nws cov lej raug txo los ntawm 4 (2 protons thiab 2 neutrons raug tshem tawm). Beta Decay . Hauv Beta Decay (minus) ib tug neutron hloov mus ua ib tug proton.

Yog li ntawd, qhov txawv ntawm alpha thiab beta lwj yog dab tsi?

Qhov sib txawv ntawm Alpha , Beta thiab Gamma radioactive lwj tuaj yeem sau tau raws li hauv qab no: Alpha lwj tsim cov khoom tshiab nrog ob tsawg dua protons thiab ob tsawg dua neutrons; Beta lwj tsim cov khoom tshiab nrog ib qho ntxiv proton thiab ib qho tsawg dua neutron.

Dab tsi tshwm sim hauv alpha thiab beta lwj? Alpha lwj : Alpha lwj yog ib hom ntawm radioactive lwj uas ib tug nucleus emits ib alpha particle (ib helium-4 nucleus). Beta lwj : Beta lwj yog ib hom ntawm radioactive lwj nyob rau hauv uas ib tug nucleus emits beta cov khoom. Tus ntxhais nucleus yuav muaj tus lej atomic ntau dua li qub nucleus.

Kuj paub yog, dab tsi yog alpha beta thiab gamma lwj?

Alpha lwj yog qhov feem ntau hauv cov ntsiab lus nrog tus lej atomic ntau dua 83. Beta lwj yog feem ntau nyob rau hauv cov ntsiab lus nrog siab neutron rau proton piv. Gamma lwj ua raws li daim ntawv: In gamma emission, tsis yog tus lej atomic lossis tus lej loj hloov pauv.

Dab tsi yog txhais los ntawm alpha lwj?

Alpha lwj los yog α - lwj yog hom radioactive lwj nyob rau hauv uas lub atomic nucleus emits ib alpha particle (helium nucleus) thiab yog li hloov los yog ' lwj ' rau hauv ib qho txawv atomic nucleus, nrog ib tug loj tus naj npawb uas yog txo los ntawm plaub thiab ib tug atomic tooj uas yog txo los ntawm ob.
