Lub caij nyoog Txhais. Hauv cov ntsiab lus ntawm chemistry thiab cov daim ntawv qhia hnub , ncua sij hawm hais txog tiam los yog rov muaj variations nyob rau hauv keeb cov khoom nrog nce atomic naj npawb. Lub caij nyoog yog tshwm sim los ntawm kev hloov pauv tsis tu ncua thiab twv tau hauv keeb atomic qauv.
Kuj tseem paub, dab tsi yog qhov ua rau lub caij nyoog nyob rau hauv lub sij hawm periodic?
Ua rau lub caij nyoog : Zoo sib xws hauv kev teeb tsa hluav taws xob ntawm valence plhaub ntawm cov ntsiab lus yog qhov tseem ceeb ua rau periodicity . Atomic naj npawb yog cov cuab yeej tseem ceeb ntawm cov khoom. Cov ntsiab lus zoo sib xws tau rov ua dua nyob rau ib ntus Thaum lawv tau teeb tsa hauv Kev Tshaj Lij Ntxiv ntawm lawv tus lej atomic.
Tom qab ntawd, lo lus nug yog, dab tsi yog periodicity Class 11? PERIODICITY . Kev rov ua dua ntawm cov khoom zoo sib xws tom qab lub sijhawm tsis tu ncua yog hu ua ncua sij hawm . Ua rau Lub caij nyoog : Cov khoom ntawm cov khoom yog cov raws sij hawm repetition ntawm zoo xws li hluav taws xob configuration ntawm lub ntsiab raws li cov atomic naj npawb nce.
Ib tug kuj yuav nug, dab tsi yog piv txwv ntawm periodicity?
npe. Lub caij nyoog yog qhov tseeb ntawm ib yam dab tsi tshwm sim ntawm lub sijhawm tsis tu ncua. Ib piv txwv ntawm periodicity yog lub hli tag nrho tshwm sim txhua 29.5 hnub. YourDictionary txhais thiab siv piv txwv.
Txoj cai ntawm periodicity yog dab tsi?
tus txoj cai tias cov khoom ntawm cov ntsiab lus yog lub sijhawm ua haujlwm ntawm lawv cov lej atomic. Kuj hu ua Mendeleev's txoj cai . (thaum chiv keeb) cov lus hais tias cov tshuaj thiab lub cev lub cev ntawm cov khoom rov tshwm sim ib ntus thaum cov ntsiab lus tau teem rau hauv qhov kev txiav txim ntawm lawv qhov hnyav atomic.

Dab tsi yog qhov txawv ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus dissociation zog?
Qhov sib txawv tseem ceeb ntawm kev sib txuas ntawm lub zog thiab lub zog bonddissociation yog tias lub zog sib txuas yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem tag nrho cov kev sib txuas ntawm tib ob hom atoms nyob rau hauv ib qho chaw sib txuas whereas daim ntawv cog lus dissociation zog yog tus nqi ntawm cov hluav taws xob xav tau los rhuav tshem ib qho kev sib koom ua ke inhomolysis
Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog cov xim muaj nyob rau hauv daim ntawv qhia kev phom sij rau kev noj qab haus huv hauv NFPA 704?
NFPA 704 pob zeb diamond kos npe siv los tso saib cov ntaub ntawv no muaj plaub ntu xim: xiav, liab, daj, thiab dawb. Txhua ntu yog siv los txheeb xyuas ib pawg sib txawv ntawm qhov muaj peev xwm txaus ntshai. Ntu xiav ntawm NFPA xim code cim qhia txog kev phom sij rau kev noj qab haus huv
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
Nyob rau theem twg S yog cov molecules tuav nyob rau hauv ib daim ntawv teev?
khov kho Ntawm no, nyob rau theem S twg yog cov molecules tuav nyob rau hauv cov duab meej? Khoom Ib yam li ntawd, qhov kub thiab txias cuam tshuam li cas rau theem hloov? Cov cua sov yog siv los rhuav tshem cov kev sib txuas ntawm cov dej khov molecules thaum lawv tig mus ua kua theem .
