Elements thiab compounds yog ob qho piv txwv ntawm cov khoom ntshiab . A yam khoom uas tuaj yeem tawg mus rau hauv cov khoom siv tshuaj lom neeg yooj yim (vim tias nws muaj ntau dua ib qho keeb ) yog a compound . Piv txwv li, dej yog a compound tsim los ntawm cov ntsiab lus hydrogen thiab oxygen.

Hais txog qhov no, vim li cas cov ntsiab lus thiab cov tebchaw suav tias yog cov tshuaj dawb huv?

Ib. 1) Elements thiab compounds yog tshuaj ntshiab vim element thiab compounds yeej ib txwm ua los ntawm tib yam hais. Dej (a compound ) ib txwm ua los ntawm (ob) Hydrogen atoms thiab (ib) Oxygenatoms.

Ib yam li ntawd, dab tsi yog lub hauv paus hauv cov khoom ntshiab? A cov khoom ntshiab muaj qhov sib xyaw ua ke tas li thiab tsis tuaj yeem muab cais ua yooj yim dua tshuaj los ntawm lub cev. Muaj ob hom cov khoom ntshiab : cov ntsiab lus thiab compounds. Cov ntsiab lus : yog tshuaj ntshiab ua los ntawm tsuas yog l hom atom. Ib qho kev sib tov yog tsim los ntawm ntau tshaj ib qho keeb los yog compound.

Dhau li ntawm qhov no, dab tsi yog cov ntsiab lus ntshiab thiab cov tebchaw?

Cov tshuaj ntshiab yog ib qho cov ntsiab lus los yog tshuaj sib xyaw . Cov ntsiab lus Tsis tuaj yeem muab cais ua lwm hom teeb meem (lub cev lossis tshuaj lom neeg). Ex: Hydrogen gas yog a cov khoom ntshiab Raws li nws yog tsim los ntawm tsuas yog Hydrogen atoms ormolecules. Carbon, kub, thiab nitrogen yog lwm yam cov ntsiab lus ( cov khoom ntshiab ).

Cov tebchaw puas suav tias yog cov tshuaj dawb huv?

A suav nrog a cov khoom ntshiab . Cov tshuaj yog tsim los ntawm kev sib xyaw ua ke ntawm ob lossis ntau tshaj ob atoms hauv qhov sib piv ruaj khov. Yog vim li cas: Yog li ntawd tshuaj sib xyaw raug kho raws li ib tug dawb huv vim tias lawv tuaj yeem tawg mus rau hauv me me tshuaj sib xyaw los yog cov khoom los ntawm kev siv tshuaj.
