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.
