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 thiaj nrhiav tau qhov zoo thiab qhov zoo?
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 thiaj nrhiav tau qhov tseeb ntawm qhov sib xyaw?
Yog tus naj npawb ntawm cov electrons nyob rau hauv lub plhaub sab nraud tsawg dua 4, ces qhov valency yog tib yam li cov xov tooj ntawm cov hluav taws xob hauv lub plhaub sab nraud. Piv txwv li, yog tias tus naj npawb ntawm valence electrons yog 2, qhov valence ntawm lub atom yog 2.
Na valency yog dab tsi?
Qhov valency ntawm chlorine yog 1. lus qhia: valency ntawm sodium atom yog +1 thiab chlorine yog −1. … sodium pub nws cov hluav taws xob sab nraud thiab chlorine atom tau txais tib lub electron kom tiav nws cov octet.
piv txwv valency yog dab tsi?
Vajtswv thiab piv txwv yog dab tsi? Ib lub ntsiab lus valence yog tus naj npawb ntawm hydrogen atomsuas tuaj yeem ua ke nrog lossis hloov (ncaj lossis tsis ncaj) ib qho ntawm cov khoom atom. Oxygen, rauPiv txwv li, muaj rau valence electrons tab sis nws valence yog 2.
