Qhov sib txawv tseem ceeb ntawm atomic thiab molecular cov ntsiab lus yog tias lub atomic keeb yog cov tshuaj lom neeg uas muaj nyob hauv cov atoms ywj siab whereas lub ntsiab molecular yog cov tshuaj molecular uas muaj ob lossis ntau dua atoms ntawm ib lub caij.

Atomic ntsiab yog cov tshuaj ruaj khov tshaj plaws; feem ntau cov noble gases. Yog li ntawd, lawv tuaj yeem nyob ua ib qho kev ywj pheej. Tab sis lawv tuaj yeem raug tshuaj lom neeg los tsim cov tebchaw thiab. Hauv qhov sib piv, cov ntsiab lus molecular yog cov tshuaj sib xyaw uas muaj tsawg kawg yog ob lub atoms ntawm tib cov tshuaj lom neeg. Cov atoms khi nrog ib leeg los ntawm kev tsim cov tshuaj sib txuas ntawm cov atoms.

Atomic Elements yog dab tsi?

Atomic cov ntsiab lus yog cov tshuaj lom neeg uas tuaj yeem muaj nyob hauv cov atoms ywj pheej. Qhov no yog vim lawv siab stability. Tsuas muaj ib qho atom hauv cov tshuaj formula ntawm cov ntsiab lus no. Yog li ntawd, tsis muaj cov lej sau npe nrog lub cim ntawm cov ntsiab lus atomic.

Daim duab 01: Txawv Noble Gases

Noble Gases

Noble gases yog pawg 8 lub ntsiab lus ntawm lub sijhawm lub sijhawm uas muaj cov khoom siv hluav taws xob ua tiav. Vim qhov kev teeb tsa hluav taws xob ua tiav no, cov atoms no tuaj yeem nyob ua ib tus neeg atoms yam tsis muaj kev sib koom ua ke. Tab sis nrog cov xwm txheej tshwj xeeb, lawv tuaj yeem tsim cov ntawv cog lus tshuaj. Cov roj zoo uas peb paub yog Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe) thiab Radon (Ra).

Dab tsi yog Molecular Elements?

Molecular cov ntsiab lus yog hom tshuaj lom neeg uas muaj tsawg kawg yog ob lub atoms ntawm tib cov tshuaj sib txuas ua ke los ntawm kev sib koom ua ke ntawm tshuaj lom neeg. Cov no yog cov sib txawv ntawm cov tshuaj sib txuas vim hais tias cov tshuaj sib xyaw muaj ob lossis ntau lub atoms ntawm cov tshuaj sib txawv.

Daim duab 01: Cov tshuaj muaj peev xwm tsim cov diatomic molecules nrog ob lub atoms ntawm tib Chemical Element.

Ntxiv mus, cov tshuaj formula ntawm cov ntsiab lus molecular muaj ib lub cim tshuaj nrog cov lej sau npe qhia txog tus lej ntawm cov atoms tam sim no hauv cov molecule qee qhov piv txwv xws li O 2, H 2, N2, Cl2, thiab lwm yam.

Qhov txawv ntawm Atomic thiab Molecular Elements yog dab tsi?

Atomic thiab molecular cov ntsiab lus, ob nqe lus piav qhia txog qhov muaj ib hom tshuaj lom neeg hauv cov hom tshuaj. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm atomic thiab molecular cov ntsiab lus yog tias lub ntsiab lus atomic yog cov tshuaj lom neeg ntawm cov atoms uas muaj tib tus naj npawb ntawm protons hauv atomic nuclei whereas molecular element yog cov khoom siv molecular uas muaj tib lub caij. Thaum xav txog lawv cov qauv tshuaj, peb tuaj yeem txheeb xyuas qhov sib txawv ntawm cov ntsiab lus atomic thiab molecular. Ntawd yog, lub ntsiab lus atomic tsuas muaj ib lub cim tshuaj uas tsis muaj tus lej sau npe thaum lub ntsiab lus molecular muaj ib lub cim tshuaj nrog tus lej sau npe.

Cov hauv qab no nthuav tawm qhov sib txawv ntawm cov ntsiab lus atomic thiab molecular hauv daim ntawv tabular.

Summary – Atomic vs Molecular Elements

Ob nqe lus, cov ntsiab lus atomic thiab molecular, piav qhia cov tshuaj lom neeg uas muaj ib hom tshuaj lom neeg ntau dua li cov tshuaj sib txawv. Qhov sib txawv tseem ceeb ntawm atomic thiab molecular keeb yog tias lub ntsiab lus atomic yog hom tshuaj atoms uas muaj tib tus naj npawb ntawm protons hauv atomic nuclei whereas molecular element yog cov khoom siv molecular uas muaj tib lub caij.
