Piv txwv li, koj tuaj yeem muaj cov poov tshuaj-37, uas muaj 18 neutrons. Potassium-38 yuav muaj 19 neutrons, poov tshuaj-39 yuav muaj 20 neutrons thiab hais txog. Ib txoj hauv kev yooj yim los nrhiav cov naj npawb ntawm cov neutrons hauv ib lub atom yuav yog saib cov atomic loj thiab rho cov naj npawb ntawm cov protons los ntawm nws.
Hauv qhov no, pes tsawg tus poov tshuaj 37 yog dab tsi?
Nws muab qib zog thiab branching piv rau atomic nuclei ntawm isotope K- 37 ( poov tshuaj , tus lej atomic Z = 19, pawg naj npawb A = 37 ).
Ib sab saum toj no, koj yuav suav pes tsawg tus neutrons hauv potassium 40 li cas? Vim lub tus naj npawb ntawm neutrons yog sib npaug rau atomic tus lej ( protons ) rho tawm los ntawm atomic mass. Yog li, 34-17 = 18.
Kuj paub, pes tsawg neutrons nyob hauv K?
Rau cov poov tshuaj nws yog hais txog 39. Qhov no txhais tau hais tias qhov hnyav atomic yog 39 rau ob qho tib si protons thiab neutrons. Txij li thaum peb paub tias tus naj npawb ntawm protons yog 19 peb tuaj yeem suav cov lej ntawm neutrons (39 19 ) ua 20.
Muaj pes tsawg neutrons nyob rau hauv poov tshuaj 39?
20
