Cov roj hluav taws xob muaj txiaj ntsig muaj tag nrho cov plhaub sab nraud ntawm cov hluav taws xob, thiab yog li tsis tuaj yeem faib lwm cov atoms 'electrons los ua daim ntawv cog lus.
Cov pa roj zoo dab tsi tuaj yeem tsim daim ntawv cog lus?
Tsuas krypton, xenon, thiab radon paub tias tsim cov tebchaw ruaj khov. Cov tebchaw ntawm noble gases yog cov muaj zog oxidizing agents (cov khoom uas zoo li tshem tawm electrons los ntawm lwm tus) thiab muaj peev xwm muaj nuj nqis raws li reagents nyob rau hauv lub synthesis ntawm lwm yam tshuaj compounds.
Yuav ua li cas cov roj hluav taws xob zoo nrog lwm cov ntsiab lus?
Noble Gases
Lawv feem ntau yog cov tshuaj inert. Qhov no txhais tau hais tias lawv tsis hnov mob nrog lwm cov ntsiab lus vim tias lawv twb muaj qhov xav tau yim tag nrho s thiab p electrons nyob rau sab nraud (siab tshaj) lub zog.
Vim li cas cov roj roj tsis sib xyaw ua ke?
Cov roj uas muaj txiaj ntsig yog cov tshuaj lom neeg hauv pawg 18 ntawm lub sijhawm teem sijhawm. Lawv yog cov ruaj khov tshaj plaws vim muaj ntau tshaj plaws ntawm valence electrons lawv lub plhaub sab nraud tuaj yeem tuav. Yog li ntawd, lawv tsis tshua muaj kev cuam tshuam nrog lwm cov ntsiab lus txij li lawv tau ruaj khov.
Vim li cas cov pa roj tsw qab tsis tsim cov lus nug yooj yim?
Cov pa roj tsw qab tsis yooj yim tsim cov tebchaw vim lawv (yog, tsis yog) tshuaj ruaj khov. Cov tshuaj lom neeg yog ib qho (force, chemical) uas tuav cov atoms ua ke hauv ib qho chaw. Chemical bonds tsim thaum atoms poob, nce, lossis (sib faib, sib faib) electrons.
