Cov ntsiab lus tuaj yeem yog chemically ua ke nyob rau hauv cov tebchaw, yog li ntawd, ib tug compound muaj ob lossis ntau lub ntsiab lus sib xyaw ua ke , nyob rau hauv meej proportions, los ntawm tshuaj txhais tau tias. Cov tshuaj yuav raug tsim los ntawm ua ke atoms ntawm lawv cov khoom cov ntsiab lus los ntawm ionic bonds los yog covalent bonds.
Ntawm no, peb hu li cas ob lossis ntau lub ntsiab lus sib xyaw ua ke?
Thaum twg ob txawv cov ntsiab lus yog chemically ua ke -i.e., tshuaj bonds tsim ntawm lawv cov atoms-qhov tshwm sim yog hu ua a tshuaj compound. Feem ntau cov ntsiab lus ntawm lub ntiaj teb daim ntawv cog lus nrog rau lwm yam cov ntsiab lus ua form tshuaj cov tshuaj, xws li sodium (Na) thiab chloride (Cl), uas ua ke los tsim lub rooj ntsev (NaCl).
Ib yam li ntawd, dab tsi yog ua los ntawm ob lossis ntau lub ntsiab lus? Ib tug compound yog ib yam khoom ua ntawm atoms ntawm ob lossis ntau qhov sib txawv . Cov khoom ntawm ib qho kev sib txuas tsis yog nyob ntawm qhov twg atoms lub compound muaj, tab sis kuj nyob ntawm seb cov atoms li cas. Piv txwv li, atoms ntawm carbon thiab hydrogen tuaj yeem ua ke ua ntau txhiab tus txawv tshuaj sib xyaw.
Kuj paub yog, ob lub ntsiab lus ua ke hu ua dab tsi?
2. Atoms sib txawv cov ntsiab lus ua tau ua ke los ua cov khoom tshiab. Ib qho molecule yog tsim thaum ob los yog ntau atoms koom ua ke chemical. Yog atoms ua ke uas yog ob los yog txawv dua cov ntsiab lus , peb hu uas yog qhov sib xyaw. Tag nrho cov tebchaw yog molecules, tab sis tsis yog tag nrho cov molecules yog cov tebchaw.
Dab tsi muaj ob lossis ntau cov tshuaj ua ke uas tsis yog tshuaj sib xyaw ua ke?
Ib qho compound muaj ob lossis ntau lub ntsiab lus tshuaj koom ua ke . Ib qho sib tov muaj ob lossis ntau dua cov khoom sib txawv uas yog tsis yog tshuaj koom ua ke . Cov tshuaj sib txawv hauv kev sib tov tuaj yeem ua tau cov ntsiab lus thiab/los yog sib xyaws.

Puas yog Oxygen yog cov khoom sib xyaw lossis sib xyaw?
Puas yog oxygen yog ib qho khoom sib xyaw lossis sib xyaw? Oxygen yog ib yam khoom. Nws yog tsim los ntawm tib hom atom, oxygen atoms (8 protons). Nws tshwm sim kom ruaj khov tshaj li molecules ntawm muaj pes tsawg leeg
Puas yog cov pa roj carbon dioxide yog qhov sib xyaw lossis sib xyaw?
CO2 yog lub npe hu ua carbon dioxide. Ib lub ntsiab yog ib yam khoom ua los ntawm ib hom atom. Cov tshuaj uas tsim cov khoom sib tov tuaj yeem yog cov khoom lossis cov khoom sib txuas, tab sis cov khoom sib tov tsis tsim cov tshuaj sib txuas. Cov khoom sib xyaw tuaj yeem sib cais rau hauv lawv cov khoom qub ib zaug ntxiv (kwv yees) yooj yim
Puas yog hluav taws xob yog cov khoom sib xyaw lossis sib xyaw?
Kev tshuaj xyuas cov ntsiab lus, cov khoom sib xyaw, thiab cov khoom sib xyaw Ionic Cov Khoom Siv Covalent Sib Nqus Sib cais rau hauv cov khoom siv hluav taws xob hauv dej kom muab cov kev daws teeb meem uas ua hluav taws xob nyob twj ywm zoo li qub molecule hauv dej thiab yuav tsis ua hluav taws xob
Puas yog Helium yog cov khoom sib xyaw lossis sib xyaw?
Helium atoms ib txwm muaj ob lub protons txhua, thiab hloov nws cov naj npawb ntawm cov protons yuav ua rau nws muaj qhov sib txawv tag nrho. Feem ntau cov khoom hauv peb lub ntiaj teb yog kev sib txuas ntawm cov ntsiab lus hu ua kev sib tov, nrog rau cov khoom sib xyaw ua ke hu ua cov tebchaw
Puas yog carbon dioxide yog cov khoom sib xyaw lossis sib xyaw?
Nws txhais tau hais tias muaj ib lub atom ntawm carbon thiab ob atoms ntawm Oxygen bonded ua ke ua ib tug molecule hu ua carbon dioxide. Ib qho molecule yog qhov tsawg tshaj plaws uas muaj peev xwm muab faib tau thiab tseem yog nws tus kheej thiab qhov sib tov yog thaum cov tshuaj tsuas yog sib xyaw ua ke xws li ntsev thiab kua txob
