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 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.
