Technically hais, alpha thiab beta lwj yog ob hom nuclear fission . Fission yog qhov tawg ntawm atom lub nucleus rau hauv me me. Qhov no tsim cov khoom uas yog ob lub protons me me tshaj niam txiv atom. Beta lwj yog qhov tawg ntawm lub nucleus los tsim ib beta particle (siab zog electron).

Tom qab ntawd, ib tug kuj yuav nug, puas yog nuclear fission beta lwj?

Fission Cov khoom lag luam muaj, qhov nruab nrab, txog tib qhov piv ntawm neutrons thiab protons raws li lawv niam txiv nucleus, thiab yog li feem ntau tsis ruaj khov rau beta lwj (uas hloov neutrons rau protons) vim hais tias lawv muaj proportionally ntau heev neutrons piv rau ruaj khov isotopes ntawm zoo xws li cov loj.

Kuj Paub, koj ua li cas alpha thiab beta lwj? Sau Alpha thiab Beta Decay Equations

  1. Lub nucleus ntawm ib qho atom faib ua ob ntu.
  2. Ib qho ntawm cov khoom no (alpha particle) mus zooming tawm mus rau hauv 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).

Xav txog qhov no, fission fusion thiab radioactive decay zoo ib yam thiab txawv li cas?

Nuclear fusion - ob lossis ntau lub nuclei me me ua ke ntawm kev kub ceev los tsim ib qho, loj dua nucleus. Ob lub hydrogen nuclei fuse los tsim ib lub helium nucleus. fusion tso tawm TON ntawm lub zog - ntau dua fission thiab radioactive lwj . Piv txwv li: Lub hnub lub zog los ntawm hydrogen atoms ua ke los ua helium.

Dab tsi ntawm fission ua rau cov tshuaj tiv thaiv kab mob?

A fission chain reaction tshwm sim thaum lub fission ntawm ib lub atom tsim cov neutrons txaus los tsim ib lossis ntau dua lwm tus cov tshuaj tiv thaiv fission (s) nyob rau hauv cov khoom fissionable, thiab qhov ntawd cov tshuaj tiv thaiv fission ua tib yam, thiab lwm yam.
