Ib qho tshwj xeeb atom yuav muaj tib tus naj npawb ntawm protons thiab electrons thiab feem ntau atoms muaj tsawg kawg li ntau neutrons li protons. Ib keeb yog ib yam khoom uas yog tsim los ntawm ib hom atom . A compound yog ib yam khoom uas ua los ntawm ob lossis ntau qhov sib txawv cov ntsiab lus uas tau chemically koom nrog.
Ntawm no, kev sib raug zoo ntawm atoms thiab cov tebchaw yog dab tsi?
txawv cov ntsiab lus ua ke ua ib compound . Qhov ntawd txhais tau tias, hydrogen tuaj yeem ua ke nrog oxygen los tsim ib qho compound hu ua 'Dej'. A compound yog ' impure ', uas txhais tau tias nws muaj ntau tshaj ib hom atom . Thaum ib pab pawg ntawm atoms ua ke, lawv tsim ib lub molecule.
Ib tug kuj yuav nug, cov ntsiab lus teb thiab cov khoom sib xyaw ua ke li cas? Cov ntsiab lus thiab tshuaj sib xyaw yog cov homogeneous nkaus xwb thiab lawv muaj qhov sib txuas tas li thoob plaws. Cov ntsiab lus thiab tshuaj sib xyaw tsis tuaj yeem muab cais rau hauv lawv cov khoom sib xws los ntawm kev siv lub cev. Compounds thiab mix yog ua los ntawm sib txawv los yog txawv atoms.
Tsis tas li ntawd, cov ntsiab lus ntawm atoms thiab cov tebchaw muaj feem cuam tshuam li cas?
Tag nrho atoms ntawm tib yam keeb muaj tib tus naj npawb ntawm protons. Atoms ntawm txawv cov ntsiab lus txawv ntawm tus naj npawb ntawm protons. Yuav ua li cas tshuaj sib xyaw txawv ntawm cov ntsiab lus ? A cov compound cov khoom sib txawv ntawm cov khoom uas ua rau cov keeb.
Kev sib raug zoo ntawm atoms molecules thiab ions yog dab tsi?
Particle tuaj yeem ua tau atoms , molecules los yog ions . Atoms yog ib qho nruab nrab hais. Molecules yog nruab nrab hais los ntawm ob los yog ntau tshaj atoms koom ua ke. Ib ion yog ib tug zoo los yog tsis zoo nqi particle.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Puas yog cov kab sib txuas ua pov thawj cov kab sib txuas?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, yog sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Dab tsi ntawm cov khoom sib txuas sib txuas muaj nyob ntawm cov dej molecules?
Piv txwv li, dej molecules yog tuav ua ke los ntawm hydrogen bonds ntawm hydrogen atom ntawm ib lub molecule thiab cov pa atom ntawm lwm tus (daim duab: hydrogen bonds). Hydrogen bonds yog ib qho muaj zog intermolecular quab yuam thiab muaj zog dua lwm cov dipole-dipole rog
Puas yog cov kab sib txuas sib txuas hauv hyperbolic geometry?
Hauv hyperbolic geometry, muaj ob hom kab sib npaug. Yog hais tias ob kab tsis sib tshuam nrog tus qauv ntawm hyperbolic geometry tab sis lawv sib tshuam ntawm nws tus ciam teb, ces cov kab yog hu ua asymptotically parallel lossis hyperparallel
