Qhov yooj yim tsev blocks uas ua teeb meem hu ua atoms. Dab tsi yog qhov sib txawv particles pom hauv atoms? (Cov lus teb: electrons, protons thiab neutrons) Lawv pom qhov twg? (Lus teb: Protons thiab neutrons pom nyob rau hauv lub nucleus, thiab electrons muaj nyob rau hauv lub plhaub nyob ib ncig ntawm lub nucleus.)

Kuj tseem yuav paub yog, dab tsi yog qhov yooj yim lub tsev thaiv ntawm teeb meem?

atom

Qhov thib ob, dab tsi yog lub tsev blocks ntawm teeb meem sawv cev los ntawm lub cim? Ua ntej cia peb saib cov ntawv: CO. Atoms muaj cov cim tshuaj lom neeg; txhua keeb tau muab ib lossis ob tsab ntawv los sawv cev rau nws. Yog li, C stands rau carbon , thiab O sawv rau oxygen (tag nrho cov cim tshuaj no tuaj yeem pom hauv daim ntawv teev sijhawm hauv daim duab 2 hauv qab no).

Tom qab ntawd, vim li cas atoms hu ua lub tsev thaiv cov teeb meem?

Atoms yog qhov yooj yim tsev blocks ntawm dog dig teeb meem . Atoms tuaj yeem koom ua ke los tsim cov molecules, uas ua rau feem ntau ntawm cov khoom nyob ib puag ncig koj. Atoms yog tsim los ntawm particle hu ua protons, electrons thiab neutrons.

Dab tsi yog lub tsev thaiv ntawm txhua qhov teeb meem quizlet?

Atoms yog cov khoom me me teeb meem . Piv txwv li, cov pa oxygen molecule yog tsim los ntawm ob lub pa oxygen atoms uas koom ua ke. Basic lub tsev thaiv rau txhua qhov teeb meem nyob hauv lub qab ntuj khwb. Nws yuav siv ntau lub atoms los ua ib yam dab tsi, piv txwv li muaj trillions thiab trillions ntawm atoms uas ua rau tib neeg lub cev.
