Qhov sib txawv tseem ceeb ntawm monatomic thiab diatomic yog tias hom monatomic muaj ib lub atom whereas hom diatomic muaj ob atoms.

Li no, qhov sib txawv ntawm monatomic thiab diatomic feem ntau yog hais txog cov atoms tam sim no hauv hom. Raws li cov npe qhia, ob lub ntsiab lus no sawv cev rau ntau lub xeev ntawm cov koom haum atomic uas 'mono' txhais tau tias 'ib' thiab 'di' txhais tau tias 'ob.' Yog li ntawd, yooj yim, monatomic txhais tau tias ib qho 'ib atom' thiab diatomic txhais tau tias 'ob lub atoms. '

Monatomic yog dab tsi?

Thaum ib lub atom tshwm sim ntawm nws tus kheej (uas tsis tshua muaj qhov teeb meem), peb hu nws monatomic. Qhov ntawd txhais tau tias, cov ntsiab lus yog nyob rau hauv lawv cov lus ntshiab. Txawm li cas los xij, qhov piv txwv nkaus xwb uas tuaj yeem nyob rau hauv pawg no yog cov pa roj carbon monoxide uas muaj nyob hauv cov atoms ntawm lawv tus kheej vim tias lawv muaj lawv lub plhaub sab nraud nrog rau tag nrho cov octet ntawm electrons. Yog li ntawd, lawv tsis saib kom txais lossis pub nyiaj ntau dua electrons kom ruaj khov dua. Yog li ntawd, noble gases ruaj khov nyob rau hauv monatomic daim ntawv. Qee qhov piv txwv yog; He – Helium, Ne – Neon, Ar – Argon, Xe – Xenon, Kr – Krypton, Rn – Radon.

Daim duab 01: Monatomic txhais tau tias muaj Ib Atoms

Tsis tas li ntawd, kuj muaj ib qho atoms hauv cov ntawv ionic tshwj xeeb hauv cov kev daws teeb meem, thiab qee qhov piv txwv yog; Na+, Ca2+, K+ thiab lwm yam. tias lawv muaj valency tas mus li. Txawm li cas los xij, muaj lwm hom ions uas muaj ntau qhov txiaj ntsig thiab tuaj yeem muaj nyob hauv ntau hom ionic, tseem yog monatomic. Ib qho piv txwv zoo yog Hlau; Fe2+ thiab Fe3+ Yog li, tsis yog cations xwb (zoo them) tab sis anions (negatively charged) kuj muaj nyob rau hauv daim ntawv monatomic; Cl, F, I– yog ob peb yam piv txwv uas muaj nyob hauv daim ntawv monatomic. Cov hom ionic no tsis ruaj khov ntawm lawv tus kheej thiab yuav ib txwm nrhiav cov khoom sib xyaw ua ke.

Tab sis, raws li tau hais los saum toj no, peb tuaj yeem pom lawv hauv kev daws teeb meem raws li hydrolysis ntawm lawv cov tebchaw. Ionic hom tsim vim tsis muaj kev ruaj ntseg ntawm ib lub atom nyob rau hauv ib tug ntshiab daim ntawv uas tsis muaj peev xwm mus cuag lub noble roj hluav taws xob configuration. Yog li ntawd, cov atoms yog txais los yog pub dawb electrons thiaj li tau txais stability.

Diatomic yog dab tsi?

Thaum ob lub atom nyob rau hauv kev sib koom ua ke, peb hu nws diatomic. Cov atoms no yuav tshwm sim tib yam lossis txawv. Thaum lawv yog ob lub atom zoo sib xws hauv kev koom tes peb hu nws 'homonuclear diatoms' thiab yog tias lawv muaj ntau hom peb hu nws 'heteronuclear diatoms'. Piv txwv ntawm qee homonuclear diatoms yuav yog O2, N2, H2, thiab lwm yam. whereas CO, TSIS MUAJ, HCl, thiab lwm yam tuaj yeem muab ua piv txwv rau heteronuclear diatoms.

Daim duab 02: Diatomic txhais tau tias muaj Ob Atoms

Peb tuaj yeem txiav txim siab diatoms ua cov sib txuas vim tias lawv tsim cov koom haum no txhawm rau kom muaj kev ruaj ntseg ntxiv los ntawm kev sib koom electrons rau ib leeg kom ob lub atoms tau txais cov roj hluav taws xob hluav taws xob zoo. Lawv tuaj yeem khi los ntawm covalent bonds los ntawm kev sib tshooj ntawm atomic orbitals los yog lwm yam lawv tuaj yeem tsim cov ionic bonds ntawm lawv, uas yog ib qho kev nyiam ntawm cov cation (zoo them) hom thiab anion (tsis zoo them) hom. Piv txwv ntawm covalent daim ntawv cog lus ntawm diatoms suav nrog CO, TSIS MUAJ, thiab lwm yam thiab peb suav tias HCl yog hom tsiaj uas muaj ionic attraction cim. Txawm li cas los xij, raws li qhov kev nyiam ntawm H+ thiab Cl– tsis muaj zog, nws tsis yog ib qho piv txwv zoo heev rau ionic bonds uas yog lwm qhov. lub ntsiab lus txhais.

Qhov txawv ntawm Monatomic thiab Diatomic yog dab tsi?

Lub sij hawm monatomic hais txog qhov muaj ib lub atom thaum lub sij hawm diatomic hais txog qhov muaj ob lub atom hauv kev sib koom ua ke. Yog li ntawd, qhov sib txawv tseem ceeb ntawm monatomic thiab diatomic yog tias hom monatomic muaj ib lub atom hos diatomic hom muaj ob atoms. Ntxiv mus, lwm qhov sib txawv ntawm monatomic thiab diatomic yog tias hom monatomic feem ntau tsis ruaj khov, tshwj tsis yog cov roj hluav taws xob zoo thaum cov hom diatomic feem ntau ruaj khov vim tias muaj cov tshuaj sib txuas ntawm ob lub atoms uas tsim los ua kom tiav cov electron octet nyob ib ncig ntawm txhua qhov. atom.

Summary – Monatomic vs Diatomic

Ob lo lus monatomic thiab diatomic piav qhia txog tus naj npawb ntawm atoms nyob rau hauv hom tshuaj. Yog li ntawd, qhov sib txawv tseem ceeb ntawm monatomic thiab diatomic yog tias hom monatomic muaj ib lub atom whereas hom diatomic muaj ob atoms.
