Los ntawm Yooj Yim rau Complex
Super me me subatomic hais yog siv los tsim qhov chaw ntawm atoms . Protons, neutrons, thiab electrons ua tau ces npaj ua daim atoms . Atoms yog ces siv los tsim cov molecules nyob ib ncig ntawm peb. Raws li peb nyuam qhuav kawm, muaj yog yuav luag 120 cov ntsiab lus uas ua tau pom hauv cov molecules peb paub.
Ib yam li ntawd, koj tuaj yeem nug, ua li cas atoms tsim teeb meem?
Atoms yog qhov yooj yim tsev blocks ntawm dog dig teeb meem . Atoms tuaj yeem koom ua ke los tsim cov molecules, uas ua rau feem ntau ntawm cov khoom nyob ib puag ncig koj. Atoms yog tsim los ntawm cov khoom hu ua protons, electrons thiab neutrons.
Tsis tas li ntawd, cov atom puas tsim cov khoom? Cov ntsiab lus . Ib keeb yog ib yam khoom ua li ntawm atoms nrog tib tus naj npawb ntawm protons. Cov ntsiab lus yog cov khoom yooj yim tshaj plaws paub. Lawv tuaj yeem yog hlau (xws li hlau, tooj liab, sodium magnesium) lossis tsis yog hlau (xws li carbon, hydrogen, oxygen, nitrogen).
Thiab cov lus nug yog, dab tsi yog atoms thiab cov ntsiab lus?) 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 . Piv txwv li, lub keeb hydrogen yog tsim los ntawm atoms tsuas muaj ib tug proton thiab ib tug electron.
Vim li cas cov ntsiab lus hu ua lub tsev thaiv cov teeb meem?
Vim tag nrho teeb meem yog tsim los ntawm ib qho keeb los yog ua ke ntawm ob los yog ntau tshaj cov ntsiab lus . Ib yam khoom ntshiab ua los ntawm ob lossis ntau dua cov ntsiab lus , chemically ua ke & hauv ib qho piv txwv.

Yuav ua li cas cov ntsiab lus hnyav dua hlau yog tsim?
Ntau lub ntsiab lus hnyav dua hlau yog tsim supernova tawg. Tus nqi ntawm lub zog tso tawm thaum lub sij hawm supernova tawg yog siab heev uas lub zog pub dawb thiab cov neutrons dawb streaming los ntawm cov tub ntxhais sib tsoo ua rau muaj kev cuam tshuam loj heev, ntev dhau los ntawm kev tsim cov hlau
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Cov nqe lus twg piav qhia vim li cas lub ntsiab lus carbon tsim muaj ntau lub tebchaw?
Cov pa roj carbon monoxide yog tib lub ntsiab lus uas tuaj yeem tsim muaj ntau lub tebchaw sib txawv vim tias txhua cov pa roj carbon atom tuaj yeem tsim plaub daim ntawv cog lus tshuaj rau lwm cov atoms, thiab vim tias cov pa roj carbon atom tsuas yog txoj cai, me me kom haum rau hauv qhov chaw ntawm cov molecules loj heev
Dab tsi yog cov lej thiab cov lej rational Yuav ua li cas cov ntsiab lus kos rau ntawm lub dav hlau sib koom tes?
Raws li peb tau hais, cov ntsiab lus ntawm lub dav hlau sib koom ua ke yog sawv cev raws li (a, b), qhov twg a thiab b yog tus lej lej. Rational cov lej yog cov lej uas tuaj yeem sau ua feem, p / q, qhov p thiab q yog tus lej. Peb hu rau x-coordinate ntawm lub point thiab peb hu b tus y-coordinate ntawm lub point
