Lub atom ntawm ib tug chemical element ua tau muaj nyob rau hauv ntau hom. Cov no yog hu ua isotopes . Lawv muaj tus ib yam tus naj npawb ntawm protons (thiab electrons), tab sis sib txawv ntawm cov neutrons. Vim txawv isotopes muaj txawv tus lej ntawm neutron, lawv ua tsis yog txhua yam hnyav ib yam los yog muaj tus ib yam pawg.

Dhau li ntawm no, nyob rau hauv txoj kev twg isotopes zoo sib xws thiab txawv?

Isotopes ntawm ib lub ntsiab yuav muaj tib yam tus naj npawb ntawm protons thiab electrons tab sis yuav txawv ntawm cov neutrons lawv muaj. Hauv lwm lo lus, isotopes muaj tib yam atomic naj npawb vim lawv tib yam element tab sis muaj a txawv atomic mass vim lawv muaj a txawv tus naj npawb ntawm neutrons.

Tsis tas li ntawd, cov isotopes ntawm hydrogen zoo li cas? Isotopes yog txawv versions ntawm tib yam element uas txhua tus muaj tib yam atomic tooj tab sis txawv tus naj npawb ntawm neutrons. Peb tuaj yeem pom ntawm no tias cov lej atomic (lossis tus naj npawb ntawm protons) ntawm isotopes ntawm hydrogen yog tib yam , tab sis lawv cov neutrons thiab atomic masses txawv.

Tsis tas li ntawd, ob qho isotopes nruab nrab ntawm tib lub caij muaj dab tsi?

Tag nrho cov atoms tib yam nruab nrab muaj tus ib yam tus naj npawb ntawm protons thiab electrons tab sis tus naj npawb ntawm neutrons tuaj yeem sib txawv. Atoms ntawm tib yam tab sis txawv neutrons hu ua isotopes.

Ob lub atom yog dab tsi isotopes ntawm ib leeg?

Hauv ib qho muab keeb , tus naj npawb ntawm neutrons yuav txawv ntawm ib leeg, thaum lub tus naj npawb ntawm protons tsis yog. Cov txawv versions ntawm tib yam keeb hu ua isotopes. Isotopes yog atoms nrog tib yam tus naj npawb ntawm protons tab sis qhov ntawd muaj ntau tus lej ntawm neutrons.
