Muaj ib ncig ntawm 32 lub ntsiab lus uas tuaj yeem pom cov ntsiab lus tsis sib xws, lub ntsiab lus lawv tsis txuas rau lwm cov ntsiab lus los tsim cov tebchaw. (ob los yog ntau tshaj qhov sib txawv atoms sib txuas ua ke). … Qee lub ntsiab lus muaj tag nrho cov valence electrons, yog li lawv ruaj khov, thiab yog li ntawd tsis ua ke nrog lwm cov ntsiab lus.
Lub xeev tsis sib koom yog dab tsi?
Lub xeev oxidation ntawm ib lub caij dawb (uncombined element) yog xoom . Rau ib qho yooj yim (monoatomic) ion, lub xeev oxidation yog sib npaug rau cov nqi ntawm cov ion. Piv txwv li, Cl– muaj lub xeev oxidation ntawm -1.
Puas yog cov hlau tsis sib xyaw?
Ores. Cov hlau tsis muaj zog xws li kubmuaj nyob hauv lub ntiaj teb cov pob zeb ua cov ntsiab lus tsis sib xyaw. Txawm li cas los xij, feem ntau cov hlau tau pom ua ke nrog lwm cov ntsiab lus los ua cov tebchaw.
Dab tsi yog cov ntsiab lus pub dawb?
Nyob hauv chemistry, lub ntsiab lus pub dawb yog cov khoom siv tshuaj uas tsis ua ke nrog lossis sib txuas nrog lwm cov ntsiab lus. Piv txwv ntawm cov ntsiab lus uas tuaj yeem tshwm sim raws li cov ntsiab lus pub dawb suav nrog cov pa oxygen molecule (O 2) thiab carbon. Tag nrho cov atoms ntawm cov ntsiab lus dawb muaj tus lej oxidation ntawm 0. Lawv tsis tshua muaj kev sib raug zoo nrog lwm cov atoms.
Dab tsi yog cov hlau tsis muaj zog tshaj plaws?
Cov hlau tsis muaj zog heev, xws li kub thiab platinum, muaj nyob hauv lub ntiaj teb pob zeb ua hlau ntshiab. Cov no hu ua cov hlau ib txwm muaj.

Vim li cas cov hmoov hlau tuaj yeem sib xyaw?
✓ Thaum siv ib lub hlau, cov hmoov yuav txawv ntawm qhov loj thiab cov duab, yog li lawv yuav tsum yog sib tov kom tau txais kev sib xws ntawm ib feem mus rau ib feem. … Lawv txo kev sib txhuam ntawm cov khoom hlau, txhim kho cov hmoov hlau ntws mus rau hauv qhov tuag, thiab txhim kho lub neej tuag.
Puas cov sib tov sib xyaw ua ke muaj cov khoom sib xws?
Ib homogeneous sib tov yog sib tov nyob rau hauv uas muaj pes tsawg leeg yog uniform thoob plaws qhov sib tov .. Qee cov ntaub ntawv hais ntxiv tias cov tshuaj lom neeg tsis tuaj yeem muab cais rau hauv nws cov ntsiab lus los ntawm kev sib cais ntawm lub cev, piv txwv li, tsis muaj kev cuam tshuam tshuaj lom neeg.
