Ib ion yog a raug them atom los yog molecule. Nws yog raug them vim hais tias tus naj npawb ntawm electrons tsis sib npaug ntawm cov protons nyob rau hauv lub atom los yog molecule. Ib qho atom tuaj yeem tau txais qhov zoo nqi los yog tsis zoo nqi nyob ntawm seb tus naj npawb ntawm cov electrons hauv ib lub atom ntau dua los yog tsawg dua tus naj npawb ntawm protons hauv atom.
Ib yam li ntawd, nws raug nug, qhov twg ion muaj tus nqi ntawm 2?
A magnesium atom yuav tsum poob ob lub electrons kom muaj tib tus lej electrons raws li ib qho atom ntawm cov pa roj carbon monoxide yav dhau los, neon. Yog li ntawd, a magnesium atom yuav tsim ib tug cation nrog ob tsawg electrons tshaj protons thiab tus nqi ntawm 2 +. Lub cim rau ion yog Mg2+, thiab hu ua a magnesium ion.
Ib tug kuj yuav nug, ua li cas koj paub cov nqi ntawm ions? Yuav nrhiav tau ionic nqi ntawm ib lub caij koj yuav tsum tau sab laj nrog koj Lub Sijhawm Table. Ntawm Lub Sijhawm Table hlau (pom nyob rau sab laug ntawm lub rooj) yuav zoo. Cov hlau tsis muaj hlau (pom nyob sab xis) yuav tsis zoo.
Puas yog ion zoo lossis tsis zoo?
Qhov ntawd txhais tau hais tias ib qho atom nrog tus nqi nruab nrab yog ib qho uas tus naj npawb ntawm electrons sib npaug rau tus lej atomic. Ions yog atoms nrog ntxiv electrons los yog tsis muaj electrons. Thaum koj plam ib qho hluav taws xob lossis ob, koj muaj a zoo nqi. Thaum koj muaj ib qho hluav taws xob ntxiv lossis ob, koj muaj ib qho tsis zoo nqi.
Cov ntsiab lus twg yog ions?
Cov hlau alkali (IA cov ntsiab lus ) poob ib qho hluav taws xob los tsim ib qho cation nrog 1+ nqi. Lub ntiaj teb alkaline hlau (IIA cov ntsiab lus ) poob ob lub electrons los ua 2+ cation. Aluminium, ib tug tswv cuab ntawm tsev neeg IIIA, poob peb electrons los ua ib qho 3+ cation. Halogens (VIIA cov ntsiab lus ) txhua tus muaj xya valence electrons.

Dab tsi yog cov txheej txheem uas nitrate ions thiab nitrite ions hloov mus rau nitrous oxide gas thiab nitrogen gas n2?
Nitrate ions thiab nitrite ions raug hloov mus rau nitrous oxide gas thiab nitrogen gas (N2). Cov cag ntoo nqus ammonium ions thiab nitrate ions siv los ua cov molecules xws li DNA, amino acids, thiab cov proteins. Organic nitrogen (cov nitrogen hauv DNA, amino acids, proteins) tawg mus rau ammonia, ces ammonium
Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
Recap • Lapse Rate yog tus nqi uas kub qis dua thaum qhov siab nce hauv huab cua • Ib puag ncig lapse tus nqi yog tus nqi uas kub qis dua thaum tus nqi tsis cuam tshuam los ntawm huab cua saturation • Environmental lapse rate txo sai dua thaum huab cua tsis ruaj khov. tsis ruaj khov
Yuav ua li cas koj thiaj nrhiav tau tus nqi siab tshaj plaws ntawm lub quadratic muaj nuj nqi?
Yog tias koj tau txais cov mis y = ax2 + bx + c, ces koj tuaj yeem pom tus nqi siab tshaj plaws uas siv cov mis max = c- (b2 / 4a). Yog tias koj muaj qhov sib npaug y = a (x-h) 2 + k thiab theatrem tsis zoo, ces qhov siab tshaj plaws yog k
Yuav ua li cas koj thiaj paub tias muaj nuj nqi yog lub zog muaj nuj nqi?
VIDEO Ib yam li ntawd, tib neeg nug, dab tsi ua rau lub zog ua haujlwm? A lub zog ua haujlwm yog a muaj nuj nqi qhov twg y = x ^n qhov twg n yog tus lej tiag tiag. Ntau tus niam txiv muaj nuj nqi xws li linear muaj nuj nqi thiab quadratic muaj nuj nqi yog qhov tseeb lub zog ua haujlwm .
