Kev lej peb tuaj yeem hais tias yog lub plhaub sab nraud ntawm lub atom muaj 4 lossis tsawg dua 4 electrons, ces qhov muaj nuj nqis ntawm ib lub caij yog sib npaug rau cov khoom siv hluav taws xob tam sim no nyob rau hauv lub plhaub sab nraud thiab yog tias nws ntau dua 4., ces qhov valency ntawm ib lub caij yog txiav txim los ntawm rho tawm tag nrho cov xov tooj ntawm electrons…
Yuav ua li cas peb xam qhov muaj nuj nqis?
Yog tias tus naj npawb ntawm cov hluav taws xob hauv lub plhaub sab nraud yog nyob nruab nrab ntawm ib mus rau plaub, qhov sib xyaw tau hais tias muaj qhov zoo. Rau cov tebchaw nrog electrons plaub, tsib, rau, los yog xya, qhov valency yog txiav txim siab los ntawm rho cov electron ntawm yim. Tag nrho cov noble gases tsuas yog Helium muaj yim electrons.
Yuav ua li cas yog lub ntsiab lus ntawm chav kawm 9?
Hint: Valency yog lub zog sib txuas ntawm lub ntsiab lus. Lub valency ntawm ib lub caij muaj feem xyuam nrog pes tsawg electrons nyob rau hauv lub plhaub sab nrauv. Lub valency ntawm ib lub caij yog tus naj npawb ntawm hydrogen atomsuas tuaj yeem ua ke nrog lossis hloov (txawm ncaj qha lossis tsis ncaj) ib lub atom ntawm lub caij.
valency chav 9 nrog piv txwv yog dab tsi?
Hint: Valency ntawm ib lub ntsiab lus txhais tau tias yog tus naj npawb ntawm hydrogen atoms uas tuaj yeem ua ke nrog lossis hloov ib lub atom ntawm lub caij, ncaj qha lossis tsis ncaj.
Isotopes Chav Kawm 9 yog dab tsi?
Isotopes: Isotopes yog atoms nrog tib tus lej ntawm protons tab sis qhov ntawd muaj tus lej sib txawv ntawm neutrons. Raws li tus naj npawb atomicsib npaug ntawm tus naj npawb ntawm cov protons thiab cov atomic loj yog cov lej ntawm cov protons thiab neutrons, isotopes yog cov ntsiab lus nrog tib tus lej atomic tab sis cov lej sib txawv.
