Zoo Siab
Yog npe molecule rau kev koom ua ke ntawm ob lossis ntau dua cov atoms los ntawm kev siv tshuaj lom neeg (ntawm tib yam lossis sib txawv ntsiab lus), tsim kom muaj kev ruaj khov. Piv txwv li: cov dej molecule yog H.20.
Molecules yog qhov faib tsawg tshaj plaws ntawm a tshuaj lom neeg yam tsis tau poob lawv lub cev-tshuaj lom neeg lub cev lossis tsis muaj qhov tshwj xeeb, thiab lawv feem ntau tsis muaj hluav taws xob zoo (tshwj tsis yog cov ions, uas yog cov lwg me me uas muaj qhov zoo lossis tsis zoo them).
Kev sib raug zoo tsim los ntawm cov qauv ntawm cov khoom qhia nws lub cev lub cev: nyob ze ua ke, nws yuav yog khoom; nrog kev txav mus los, nws yuav yog a kua; thiab kom tau nthuav dav ntau yam yam tsis cais cais tawm, nws yuav yog roj.

Hom tshuaj molecules
Molecules tuaj yeem raug cais raws li lawv qhov sib xyaw atomic, uas yog:
Ntse. Ua los ntawm kev txhais thiab tshwj xeeb tus naj npawb ntawm atoms, ib qho ntawm cov ntsiab lus sib txawv lossis tib yam. Nyob rau hauv lem, classifiable raws li tus naj npawb ntawm sib txawv atoms uas tau koom ua ke rau hauv nws cov qauv, hauv:
- Monoatomic (1 hom tib yam ntawm atom),
- Diatomic (ob hom),
- Trichotomous (peb hom),
- Tetralogical (plaub hom) thiab ntxiv rau.
Macromolecules lossis polymers. Macromolecules yog cov saw loj molecular ua los ntawm cov khoom yooj yim koom ua ke los tsim cov kev tsim kho nyuaj dua.
Cov qauv sau tseg ib txwm muaj ntawm cov lwg me me tau hais tawm hauv kev sib raug zoo nrog cov ntsiab lus atomic tam sim no, siv cov cim ntawm cov lus sib tham los sawv cev rau cov ntsiab lus koom nrog thiab cov ntawv sau me me uas nthuav qhia lawv cov lej sib xws hauv cov qauv.
Txawm li cas los xij, txij li cov lwg me me yog cov khoom peb sab, cov qauv pom pom uas cuam tshuam txog cov qauv thiab tsis yog qhov ntau ntawm nws cov ntsiab lus feem ntau siv rau lawv txoj kev nkag siab.
