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.

Puas yog cov ntsiab lus ntawm cov teeb meem txav qhov nruab nrab ntawm lawv teb?
Cov khoom tsis tuaj yeem txav mus los. Ib qho piv txwv ntawm cov khoom khib nyiab thiab cov kua dej yog cov khoom sib txuas nrog lawv cov neeg nyob ze, uas yog, nrog rau lwm cov khoom. Yog li lawv yog incompressible thiab qhov sib txawv ntawm cov khib nyiab thiab kua distinguishesthem los ntawm gases
Lub tsev thaiv ntawm qhov teeb meem yog dab tsi?
Lub hauv paus tsev blocks uas tsim 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.)
Cov organic tebchaw tau txais lawv lub npe Li cas lo lus muaj feem xyuam rau nws lub ntsiab lus li cas?
Lo lus hais txog nws lub ntsiab lus li cas? Organic Compounds tau txais nws lub npe los ntawm tus lej ntawm cov ntawv cog lus carbon. Lo lus muaj feem xyuam rau lub ntsiab lus vim hais tias nws yuav tsum tau ua nrog bonds nyob rau hauv carbon atoms nyob rau hauv cov organic tebchaw
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Cov nqe lus twg piav qhia vim li cas lub ntsiab lus carbon tsim muaj ntau lub tebchaw?
Cov pa roj carbon monoxide yog tib lub ntsiab lus uas tuaj yeem tsim muaj ntau lub tebchaw sib txawv vim tias txhua cov pa roj carbon atom tuaj yeem tsim plaub daim ntawv cog lus tshuaj rau lwm cov atoms, thiab vim tias cov pa roj carbon atom tsuas yog txoj cai, me me kom haum rau hauv qhov chaw ntawm cov molecules loj heev
