Qhov no yog vim cov tshuaj khoom nyob ntawm tsis muaj valence electrons. Raws li hauv a pab pawg tag nrho cov ntsiab lus muaj ib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov khoom zoo sib xws mas in a lub sij hawm qhov tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv hauv tshuaj muaj zog.
Ib sab ntawm no, puas muaj cov khoom siv tshuaj zoo sib xws hauv tib lub sijhawm lossis pab pawg?
Cov tshuaj lom neeg yog teem nyob rau hauv kev txiav txim ntawm nce atomic tooj. Cov kab kab rov tav hu ua lub sij hawm thiab cov kab ntsug yog hu ua pab pawg . Cov ntsiab lus hauv tib pawg muaj cov khoom zoo sib xws . Qhov no yog vim lawv muaj cov ib yam tus naj npawb ntawm cov electrons sab nraud thiab cov ib yam valency.
Ib tug kuj yuav nug, cov ntsiab lus hauv ib pab pawg lossis lub sijhawm zoo sib xws? Cov kab ntsug ntawm lub rooj ntu ntu hu ua pab pawg los yog tsev neeg vim lawv zoo sib xws tshuaj lom neeg tus cwj pwm. Tag nrho cov tswv cuab ntawm ib tsev neeg ntawm cov ntsiab lus muaj tib tus naj npawb ntawm valence electrons thiab zoo sib xws tshuaj muaj zog. Cov kab kab rov tav ntawm lub rooj ntu ntu hu ua lub sij hawm.
Ntawm no, cov ntsiab lus hauv tib lub sijhawm muaj qhov sib xws?
Koj muaj koj Lub sijhawm Tag nrho cov cov ntsiab lus hauv a lub sijhawm muaj tus ib yam tus naj npawb ntawm atomic orbitals. Piv txwv li, txhua keeb nyob rau hauv kab saum toj kawg nkaus (thawj lub sij hawm ) muaj ib lub orbital rau nws cov electrons. Tag nrho cov cov ntsiab lus nyob rau hauv kab thib ob (thib ob lub sij hawm ) muaj ob lub orbitals rau lawv cov electrons.
Vim li cas cov khoom ntawm cov ntsiab lus tau muab tso rau hauv tib pab pawg ntawm lub rooj zaum zoo sib xws?
Cov ntsiab lus hauv tib pawg (hauv daim ntawv qhia hnub ) muaj zoo sib xws tshuaj khoom . Qhov no yog vim lawv cov atoms ib yam tus naj npawb ntawm electrons nyob rau hauv lub siab tshaj plaws nyob qib zog. Pab pawg 1 cov ntsiab lus yog cov hlau reactive hu ua alkali hlau. Pab pawg 0 cov ntsiab lus yog unreactive non-metals hu ua noble gases.

Dab tsi yog lub ntsiab lus ntawm ib pab pawg ntawm cov lus teev sijhawm?
Nyob rau hauv chemistry, ib pab pawg (tseem hu ua tsev neeg) yog ib kem ntawm cov ntsiab lus nyob rau hauv lub sij hawm lub sij hawm ntawm cov tshuaj. Muaj 18 pawg lej nyob rau hauv daim ntawv teev sijhawm; cov kab f-block (nruab nrab ntawm pawg 3 thiab 4) tsis suav nrog
Puas yog ob txoj kab sib luag zoo sib xws lossis tsis sib xws?
Yog tias ob qhov sib npaug piav txog kab sib luag, thiab yog li cov kab uas tsis sib tshuam, qhov system yog ywj siab thiab tsis sib haum. Yog hais tias ob qhov sib npaug piav txog tib kab, thiab yog li cov kab uas hla tus lej tsis kawg, lub kaw lus yog nyob ntawm thiab sib xws
Yuav ua li cas lub abundance ntawm lub ntiaj teb no piv nrog cov abundance ntawm lub ntsiab nyob rau hauv tib neeg?
Oxygen yog cov khoom muaj ntau tshaj plaws hauv ntiaj teb thiab hauv tib neeg. Kev nplua nuj ntawm cov ntsiab lus uas tsim cov organic tebchaw nce hauv tib neeg thaum qhov kev nplua nuj ntawm metalloids nce hauv ntiaj teb. Cov ntsiab lus uas muaj ntau hauv ntiaj teb yog qhov tseem ceeb los txhawb txoj sia
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Vim li cas cov ntsiab lus hauv tib pab pawg muaj nqi tib yam?
Feem ntau, cov ntsiab lus uas koom nrog tib pab pawg (kab ntsug) ntawm lub rooj sib tham hauv lub sijhawm ions nrog tib tus nqi vim lawv muaj tib tus lej ntawm valence electrons
