Koj pab pawg txhais li cas ntawm lo lus “ particle raws li nws yog siv hauv chemistry ? A particle yog ib qho atom los yog pab pawg ntawm cov atoms uas sib koom ua ke thiab ua haujlwm ua ib chav. · Cov lus teb yuav txawv.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog lub ntsiab lus ntawm particle hauv chemistry?
Kev txhais ntawm Particle . A particle yog ib feem me me ntawm qhov teeb meem. Lo lus encompasses ib tug enormous ntau ntawm qhov ntau thiab tsawg: los ntawm subatomic cov khoom , xws li electrons, to cov khoom loj txaus kom pom, xws li cov khoom ntawm plua plav ntab hauv hnub ci.
Ib tug kuj yuav nug, dab tsi yog qhov txawv ntawm ib tug atom thiab ib tug particle? Cov khoom tuaj yeem yog atoms , molecules los yog ions. Atoms yog ib leeg nruab nrab cov khoom . Molecules yog nruab nrab cov khoom ua los ntawm ob lossis ntau dua atoms koom ua ke.
Tsuas yog li ntawd, hom particles hauv chemistry yog dab tsi?

Nws txhais li cas los sau koj cov lus teb nyob rau hauv cov nqe lus ntawm pi?
Cov lus teb meej txhais tau tias koj tsis xav tau lub tshuab xam zauv, tsuas yog tso koj cov lus teb kawg uas qhia txog Pi. Lub voj voog ntawm lub voj voog tuaj yeem pom siv cov qauv C = Pid. C yog qhov ncig (qhov perimeter) thiab d yog txoj kab uas hla. Yog li hauv paus koj tsuas yog yuav tsum tau muab txoj kab uas hla los ntawm Pi
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Qhov nruab nrab ntawm pawg thiab hauv pab pawg txhais li cas?
