Cov ntsiab lus tuaj yeem ua tau chemically ua ke rau hauv tshuaj sib xyaw , yog li ntawd, a compound muaj ob lossis ntau lub ntsiab lus ua ke , nyob rau hauv meej proportions, los ntawm tshuaj txhais tau tias. Cov tshuaj tej zaum yuav tsim los ntawm ua ke atoms ntawm lawv cov ntsiab lus los ntawm ionic bonds los yog covalent bonds.
Tsis tas li lo lus nug yog, puas yog cov khoom sib txuas ntawm lub cev lossis tshuaj ua ke?
Hauv ib compound cov (atoms / molecules) yog ( chemically lub cev ) ua ke yog li ntawd cov ntsiab lus uas ua rau cov compound (tshem / poob) lawv tus kheej thiab (tsis txhob) coj cov khoom tshiab. Qhov tsawg tshaj plaws uas qhia tau tus kheej ntawm a compound yog a(n) molecule uas yog tsim los ntawm atoms uas yog tshuaj ua phooj ywg.
Tom qab ntawd, lo lus nug yog, yuav ua li cas tshwm sim thaum cov khoom sib xyaw ua ke? Cov tshuaj. Thaum ob qhov sib 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).
Qhov thib ob, yog cov tshuaj sib xyaw ua ke?
Tshuaj bonds yog xav tau rau cov khoom yuav tsum tau ua ke tshuaj . Kev daws teeb meem yog ua ke ntawm cov khoom uas tau koom ua ke los ntawm kev sib cuam tshuam los yog ionic rog. A daws tuaj yeem sib cais los ntawm kev hloov ntawm lub cev, xws li boiling cov kuab tshuaj.
Puas yog kev sib xyaw ua ke ntawm kev sib raug zoo?
Sib tov : A sib tov muaj ob lossis ntau yam khoom (cov ntsiab lus, lattices, molecules, compounds), uas tsis yog chemically bonded ua ke.

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 kev sib xyaw cov khoom xyaw rau lub ncuav mog qab zib yog tshuaj lom neeg?
Cov ntaub ntawv yooj yim ntawm kev sib cais thiab sib xyaw yog suav tias yog kev hloov pauv ntawm lub cev, tab sis kev sib xyaw cov khoom xyaw ntawm lub ncuav mog qab zib tsis yog ib qho kev sib xyaw yooj yim. Kev hloov tshuaj pib tshwm sim thaum cov khoom xyaw sib xyaw, tsim cov tshuaj tshiab
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
