Cov atoms ntawm cov khoom siv tshuaj muaj peev xwm muaj nyob hauv ntau hom. Cov no hu ua isotopes . Lawv muaj ib yam tus naj npawb ntawm protons (thiab electrons), tab sis sib txawv ntawm cov neutrons. txawv isotopes ntawm ib yam element muaj ntau pawg.
Tsis tas li ntawd, dab tsi atoms ions thiab isotopes muaj sib xws?
Ib atom yog qhov tsawg tshaj plaws ntawm lub caij uas tuaj yeem nyob ib leeg lossis ua ke nrog lwm yam atoms . Isotopes yog atoms uas muaj tib tus naj npawb ntawm protons tab sis txawv tus lej ntawm neutrons. Ib ion yog ib atom los yog molecule nrog tus nqi zoo lossis tsis zoo.
Tsis tas li ntawd, cov atoms twg yog isotopes ntawm ib leeg? Hauv ib qho muab keeb , tus naj npawb neutrons tuaj yeem sib txawv ntawm ib leeg, thaum tus naj npawb ntawm protons tsis yog. Cov txawv versions ntawm tib yam keeb hu ua isotopes. Isotopes yog atoms nrog tib tus lej ntawm protons tab sis qhov ntawd muaj tus lej sib txawv neutrons.
Ntawm no, ions thiab isotopes zoo sib xws thiab txawv li cas?
Ib ion yog ib qho atom uas muaj cov nqi hluav taws xob vim qhov poob lossis nce ntawm ib lossis ntau dua electrons. Ib isotope yog txhua yam ntawm ob lossis ntau hom ntawm tib lub caij uas muaj cov lej sib npaug ntawm cov protons tab sis txawv Cov naj npawb ntawm cov neutrons hauv lawv cov nuclei, thiab yog li txawv ntawm cov txheeb ze atomic mass tab sis tsis nyob rau hauv cov khoom siv tshuaj.
Yuav ua li cas yuav ib txwm txawv nyob rau hauv lub isotopes ntawm atoms?
Isotopes yog atoms nrog txawv atomic pawg uas muaj tib yam atomic tus lej. Cov atoms ntawm txawv isotopes yog atoms ntawm tib yam tshuaj lom neeg; lawv txawv nyob rau hauv tus naj npawb ntawm neutrons nyob rau hauv lub nucleus.
