Atoms ntawm tib lub caij, muaj tib yam tus naj npawb ntawm protons , tab sis txawv tus lej ntawm neutrons , yog hu ua isotopes. Isotopes ntawm cov khoom muab tag nrho muaj tib yam tus naj npawb ntawm protons , yog li lawv muaj tib yam tus lej atomic (piv txwv li tus lej atomic ntawm helium yog ib txwm 2).

Yog li ntawd, cov atoms twg yog isotopes ntawm tib lub caij?

Isotopes yog cov atoms ntawm tib lub caij uas muaj cov lej sib txawv neutrons tab sis tib yam tus naj npawb ntawm protons thiab electrons. Qhov txawv ntawm tus naj npawb ntawm neutrons nruab nrab ntawm ntau yam isotopes ntawm ib lub caij txhais tau hais tias ntau yam isotopes muaj ntau qhov sib txawv.

Ib yam li ntawd, cov ntsiab lus twg yog isotopes? Tag nrho cov ntsiab lus muaj tus lej isotopes . Hydrogen muaj tsawg tus lej ntawm isotopes nrog peb xwb. Cov cov ntsiab lus nrog ntau tshaj isotopes yog cesium thiab xenon nrog 36 paub isotopes . Ib txhia isotopes yog ruaj khov thiab qee qhov tsis ruaj khov.

Khaws qhov no hauv kev txiav txim siab, qhov twg ob lub ntsiab lus sawv cev rau isotopes ntawm tib lub caij?, qhov twg A yog tus lej loj, Z yog tus lej atomic, thiab X yog tsab ntawv cim ntawm tus keeb . Isotopes : Atoms ntawm tib yam nrog ib yam atomic tooj tab sis txawv cov lej raug hu isotopes . Isotopes muaj qhov sib npaug ntawm cov protons tab sis tus naj npawb ntawm neutrons yog txawv.

Koj paub li cas cov atoms yog isotopes?

Saib ntawm lub atom nyob rau hauv lub sij hawm ntawm lub ntsiab lus thiab nrhiav pom nws lub atomic mass yog dab tsi. Tshem tawm tus naj npawb ntawm protons los ntawm atomic mass. Qhov no yog tus naj npawb ntawm neutrons uas niaj hnub version ntawm lub atom muaj. Yog tus naj npawb ntawm neutrons nyob rau hauv muab atom yog txawv, tshaj nws yog ib isotope.
