Raws li ib tug atom hluav taws xob nruab nrab , ib lub atom yeej ib txwm muaj tib tus lej ntawm electrons (tsis zoo nqi) thiab protons (tus nqi zoo). Neutrons, ntawm chav kawm, yog nruab nrab . Tshem tawm tus naj npawb ntawm protons (8) thiab koj tau txais tus naj npawb ntawm neutrons, uas yog 8. Lwm qhov piv txwv: Hlau yog 26fe56.
Ib yam li ntawd, koj yuav nug, puas yog hluav taws xob nruab nrab?
Los ntawm txhais, atom yog hluav taws xob nruab nrab (piv txwv li muaj tib tus naj npawb ntawm protons li nws ua electrons, ntxiv rau qee tus lej ntawm neutrons nyob ntawm isotope). Yog tias hom tsiaj raug them, nws raug xa mus rau ion (cation for positively charged and anion for negatively charged species), kuj yog txhais.
Tsis tas li ntawd, cov ntsiab lus nruab nrab yog dab tsi? A nruab nrab atom yog ib qho atom uas tus nqi ntawm cov electrons thiab cov protons sib npaug. Luckily, ib qho hluav taws xob muaj tib lub nqi (nrog rau qhov sib txawv) ua ib qho proton. Piv txwv li: Carbon muaj 6 protons. Cov nruab nrab Carbon atom muaj 6 electrons.
Hais txog qhov no, puas yog tag nrho cov ntsiab lus muaj tus nqi nruab nrab?
Txij li thaum atoms muaj cov lej sib npaug ntawm protons thiab electrons, thiab txij li cov ntsiab lus yog tsim los ntawm atoms, tag nrho tus cov ntsiab lus yog nruab nrab . Qee zaum hauv kev sib xyaw, ib keeb tej zaum yuav poob los yog nce ib qho hluav taws xob, tsim ib qho ion.
Lub Ray twg yog hluav taws xob nruab nrab?
Hom thib peb ntawm ionizing hluav taws xob suav nrog gamma thiab X rays, uas yog electromagnetic, indirect ionizing hluav taws xob. Cov no yog indirect ionizing vim hais tias lawv yog hluav taws xob nruab nrab (raws li tag nrho cov electromagnetic radiations) thiab tsis cuam tshuam nrog atomic electrons los ntawm coulombic rog.

Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Lub co2 hluav taws tua hluav taws puas ua haujlwm ntawm hluav taws kub oxidizer?
Lub tshuab tua hluav taws xob carbon dioxide tsis yog qhov kev xaiv zoo rau kev tua hluav taws oxidizer vim nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tsis suav nrog cov pa oxygen, thiab cov pa oxygen atmospheric tsis xav tau rau hluav taws kub oxidizer. Cov tshuaj tua hluav taws qhuav qhuav kuj tseem yuav siv tsis tau rau feem ntau
