Cov ntsiab lus no tau suav tias yog inert gases mus txog rau xyoo 1960, vim lawv oxidation naj npawb ntawm 0 tiv thaiv cov cov pa roj los ntawm kev sib txuas yooj yim. Tag nrho cov pa roj muaj qhov siab tshaj plaws tus lej ntawm electrons ua tau nyob rau hauv lawv lub plhaub sab nrauv (2 rau Helium, 8 rau tag nrho lwm tus), ua rau lawv ruaj khov.

Ntawm no, vim li cas lub xeev oxidation ntawm noble gases feem ntau yog xoom?

Txij li thaum cov pa roj tsis txhob ua daim ntawv cog lus nrog lwm cov ntsiab lus, lawv tsis raug muab rau ib qho twg oxidation xeev . Raws li cov pa roj muaj qhov sib npaug zoo ntawm electrons nyob rau hauv tag nrho lawv cov valence shells, nws yuav nyuaj ua rau lawv poob los yog nce electrons raws li qhov yuav ua rau cov qauv tsis ruaj khov.

Ib tug kuj yuav nug, dab tsi yog oxidation tooj ntawm alkali hlau? Alkali hlau muaj ib tug electron nyob rau hauv lawv valence s-orbital thiab yog li ntawd lawv oxidation xeev yuav luag ib txwm +1 (los ntawm poob nws) thiab alkaline ntiaj teb hlau muaj ob lub electrons nyob rau hauv lawv valences-orbital, uas ua rau ib tug oxidation xeev ntawm +2 (los ntawm poob ob qho tib si).

Raws li txoj cai, tus lej oxidation rau pawg 18 yog dab tsi?

Xenon muaj ntau yam chemistry nyob rau hauv Pawg 18 thiab nthuav tawm cov oxidation xeev +1/2, +2, +4, +6, thiab +8 hauv cov tebchaw nws tsim.

4 Noble gases yog dab tsi?

Noble gases, nyob rau hauv kev txiav txim ntawm lawv ceev, yog helium, neon, argon , krypton ua , xenon thiab radon . Lawv hu ua noble gases vim hais tias lawv yog heev majestic uas, feem ntau, lawv tsis hnov qab dab tsi. Vim li no lawv tseem hu ua inert gases.
