Yog li ntawd Helium tsuas muaj 2 leeg xwb electrons . Nws tau muab tso rau hauv Pawg 8A vim tias nws lub plhaub sab nrauv yog tag nrho nrog ob electrons . Thaum koj kos lub Lewis qauv rau Helium koj yuav muab ob " dots "los yog valance electrons nyob ib ncig ntawm lub cim cim (Nws).
Nyob rau hauv no hais txog, dab tsi yog lub electron dot daim duab rau lithium?
Electron Dot Daim duab
| lithium | 1 s ib 2 2 s ib 1 | 1 valence electron |
|---|---|---|
| beryllium | 1 s ib 2 2 s ib 2 | 2 valence electrons |
| nitrogen | 1 s ib 2 2 s ib 2 2 ib p 3 | 5 valence electrons |
| neon | 1 s ib 2 2 s ib 2 2 ib p 6 | 8 valence electrons |
Dab tsi yog daim duab kos duab electron rau Argon? Argon yog ib qho zoo kawg nkaus roj, thiab xws li muaj 8 valence electrons . Txhua yam koj tau ua yog sau Ar nrog 8 dots nyob ib ncig ntawm nws.
Tsis tas li ntawd, Lewis dot daim duab rau Helium yog dab tsi?
Cov Lewis cim rau helium : Helium yog ib tug ntawm cov noble gases thiab muaj tag nrho valence plhaub. Tsis zoo li lwm cov pa roj hauv pawg 8, Helium tsuas muaj ob lub valence electrons. Hauv Lewis cim, cov electrons yog depicted li ob leeg ib khub dots.
Muaj pes tsawg electrons nyob hauv Na +?
Ib qho Na + ion yog sodium atom uas tau poob ib qho hluav taws xob uas ua rau cov xov tooj hluav taws xob hauv lub atom sib npaug rau qhov ze tshaj plaws Nobel roj Neon uas muaj 10 electrons . Qhov no tag nrho ua rau 1st thiab 2nd electron plhaub. Sodium atom muaj 11 protons, 11 electrons thiab 12 neutron.

Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Dab tsi yog qhov txawv ntawm daim duab thiab daim duab?
Ib daim duab yog ib daim duab ntawm kev ua lej, tab sis kuj siv tau (loos) txog ib daim duab ntawm cov ntaub ntawv txheeb cais.A daim duab yog ib daim duab sawv cev ntawm cov ntaub ntawv, qhov twg ib kab ntawv yog ib daim ntawv
Qhov kev hloov pauv twg yuav hloov daim duab A rau hauv daim duab B?
Ob daim duab tau hais tias yuav sib haum xeeb yog tias ib tus tuaj yeem tau txais los ntawm lwm tus los ntawm ib ntu ntawm kev txhais lus, kev xav, thiab kev sib hloov. Cov duab sib xws muaj qhov loj thiab zoo tib yam. Txhawm rau hloov daim duab A rau hauv daim duab B, koj yuav tsum xav txog nws hla y-axis thiab txhais ib chav nyob rau sab laug
Daim duab qhia chaw muaj txiaj ntsig dab tsi tshaj li daim duab?
Daim duab saum toj kawg nkaus muaj qhov zoo hauv qab no ntawm daim duab qhia: (1) Nws muab cov duab pom hauv av tam sim no uas tsis muaj daim ntawv qhia sib npaug. (2) Nws tau yooj yim dua. Daim duab yuav nyob rau hauv txhais tes ntawm tus neeg siv nyob rau hauv ob peb teev tom qab nws coj; daim ntawv qhia yuav siv sij hawm ntau lub hlis los npaj
Dab tsi yog qhov txawv ntawm lub xeev daim duab kos duab thiab daim duab ua haujlwm?
Lub xeev daim duab qauv yog siv los qhia qhov sib lawv liag ntawm lub xeev uas ib yam khoom mus dhau, qhov ua rau kev hloov ntawm ib lub xeev mus rau lwm qhov thiab qhov kev txiav txim uas tshwm sim los ntawm lub xeev hloov. Daim duab ua haujlwm yog ntws ntawm kev ua haujlwm yam tsis muaj qhov tshwm sim (kev tshwm sim) mechanism, lub xeev tshuab yog suav nrog lub xeev triggered
