Yog vim li cas cov ntsiab lus hu ua lub tsev blocks ntawm teeb meem ? Vim tag nrho teeb meem yog tsim los ntawm ib qho keeb los yog ua ke ntawm ob los yog ntau tshaj cov ntsiab lus . Ib yam khoom ntshiab ua los ntawm ob lossis ntau dua cov ntsiab lus , chemically ua ke & hauv ib qho piv txwv.

Hais txog qhov no, dab tsi yog cov ntsiab lus hu ua lub tsev blocks ntawm teeb meem?

Qhov yooj yim tsev blocks uas ua teeb meem yog 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.)

Tsis tas li ntawd, dab tsi yog qhov teeb meem thiab cov ntsiab lus? Teeb meem yog cov khoom uas tsim txhua yam hauv lub qab ntuj khwb. Cov khoom, kua, roj, thiab ntshav yog tag nrho teeb meem . Thaum tag nrho cov atoms uas tsim ib yam khoom yog tib yam, ces cov khoom ntawd yog ib qho keeb . Cov ntsiab lus yog tsim los ntawm ib hom atom xwb. Vim li no, cov ntsiab lus yog hu ua "ntshiab" tshuaj.

Yog li ntawd, lub tsev thaiv ntawm qhov teeb meem yog dab tsi?

Cov kws tshawb fawb ib zaug xav tias qhov tseem ceeb tshaj plaws tsev thaiv qhov teeb meem yog ib tug particle hu ua atom. Tam sim no peb paub tias lub atom yog tsim los ntawm ntau daim me me, hu ua subatomic hais. Txhua lub atom muaj lub hauv paus tseem ceeb hu ua nucleus, ua los ntawm cov khoom hu ua protons thiab neutrons.

Yuav ua li cas yog lub hauv paus tsev blocks ntawm 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 tsev thaiv rau tag nrho 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.
