Qhov no qhia tau hais tias chlorine muaj 7 valence electrons nyob rau hauv nws lub plhaub sab nraud. Raws li, qhov valency ntawm chlorine yog 7-8 uas yog -1.
Koj yuav pom qhov zoo li cas?
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 koj yuav pom qhov muaj txiaj ntsig ntawm chlorine thiab magnesium Class 9?
As magnesium muaj 2 valence electron, nws valency yog 2. Raws li, valency ntawm chlorine yog 7-8 uas yog -1. Yog li qhov valency ntawm Mg yog 2, qhov chlorine nws yog -1 hauv MgCl2.
Yuav ua li cas koj thiaj pom qhov muaj txiaj ntsig ntawm chlorine 17 Sulfur 16 thiab magnesium 12)?
Magnesium atom muaj 12 electrons, yog li nws cov electron configuration yog K L M2, 8, 2. Ib magnesium atom muaj 2 electrons nyob rau hauv nws lub plhaub sab nraud (M plhaub). Ib tug magnesium atom tuaj yeem poob nws 2 sab nraud electrons kom ua tiav cov roj hluav taws xob tsis zoo (ntawm 8 valence electrons), yog li qhov muaj txiaj ntsig ntawm magnesium yog 2.
Vim li cas valency ntawm magnesium yog 2?
Magnesium muaj qhov sib npaug sib npaug 2 + vim tias lub teeb tsa hluav taws xob ntawm Mg yog [2, 8, 2]. Qhov ze tshaj plaws noble roj rau magnesium yog neon nrog hluav taws xob configuration ntawm [2, 8], rauua tiav qhov kev teeb tsa hluav taws xob ruaj khov Mg tuaj yeem poob 2 valence electrons, yog li nws qhov valency yog 2 +.
