Isotopes yog hluav taws xob nruab nrab vim lawv muaj tus lej sib npaug ntawm cov protons (+) thiab electrons (-).
Yog li, ua li cas koj thiaj paub tias isotope nruab nrab?
Txiav txim siab tus naj npawb ntawm electrons siv tus lej atomic. Lub atom muaj ib tug nruab nrab tus nqi, yog li tus nqi zoo thiab tsis zoo yog sib npaug rau ib leeg. Tus naj npawb atomic kuj yog tus naj npawb ntawm electrons. Xam cov naj npawb ntawm cov neutrons los ntawm kev noj cov lej loj thiab rho tawm tus naj npawb ntawm cov protons pom hauv cov nucleus.
Kuj Paub, dab tsi ua rau ib qho isotope? Cov atoms ntawm cov khoom siv tshuaj muaj peev xwm muaj nyob hauv ntau hom. Cov no hu ua isotopes . Lawv muaj tib tus naj npawb ntawm protons (thiab electrons), tab sis sib txawv ntawm cov neutrons. txawv isotopes ntawm tib lub ntsiab muaj ntau pawg. Mass yog lo lus rau ntau npaum li cas cov khoom (los yog teeb meem) ib yam dab tsi muaj.
Ntawm no, puas yog isotopes them?
Protons nqa qhov zoo nqi thiab electrons nqa qhov tsis zoo nqi . Cov isotope ntawm ib lub caij tseem muaj tib tus lej ntawm protons, yog li nws muaj tib tus lej atomic. Isotopes kuj muaj tib cov xov tooj ntawm electrons. Qhov sib txawv tseem ceeb ntawm isotopes ntawm tib lub ntsiab yog tias lawv txawv tus lej ntawm neutrons.
Dab tsi yog isotopes thiab piv txwv?
Cov ntsiab lus yog txhais los ntawm tus naj npawb ntawm protons hauv atomic nucleus. Rau piv txwv Ib qho atom nrog 6 protons yuav tsum yog carbon, thiab atom nrog 92 protons yuav tsum yog uranium. Ntxiv nrog rau cov protons, cov atoms ntawm yuav luag txhua lub caij tseem muaj cov neutrons. Cov no isotopes yog hu ua carbon-12, carbon-13 thiab carbon-14.

Yuav ua li cas isotopes txawv ntawm nruab nrab atoms ntawm tib lub caij?
Isotopes yog atoms nrog tib tus naj npawb ntawm protons tab sis muaj ntau tus lej ntawm neutrons. Txij li thaum tus naj npawb atomic sib npaug ntawm cov protons thiab cov atomic loj yog cov lej ntawm protons thiab neutrons, peb tuaj yeem hais tias isotopes yog cov ntsiab lus nrog tib tus lej atomic tab sis cov lej sib txawv
Yuav ua li cas koj pom qhov nruab nrab thiab nruab nrab ntawm daim duab peb sab?
Txhawm rau nrhiav qhov chaw nruab nrab ntawm daim duab peb sab, nws yog qhov yooj yim tshaj plaws los kos tag nrho peb qhov nruab nrab thiab nrhiav lawv qhov kev sib tshuam. Txhawm rau kos qhov nruab nrab ntawm daim duab peb sab, ua ntej nrhiav qhov nruab nrab ntawm ib sab ntawm daim duab peb sab. Kos ib kab ntu uas txuas qhov taw tes no mus rau qhov rov qab vertex
