Feem ntau, cov ntsiab lus uas belongs rau tib pawg (ntsug kem) ntawm lub sij hawm lub rooj daim ntawv ions nrog rau tib nqi vim lawv muaj ib yam tus naj npawb ntawm valence electrons.

Ua raws li qhov no, vim li cas cov ntsiab lus hauv tib pab pawg?

1 Teb. Cov cov ntsiab lus hauv tib pab pawg muaj cov lej zoo sib xws ntawm valence electrons. Lawv muaj tus lej ntawm cov electrons zoo tib yam hauv lawv lub plhaub sab nraud. e.g. Tag nrho cov alkali hlau nyob rau hauv Pab pawg 1 muaj 1 valence electron, yog li lawv txhua tus zoo li hnov mob ib yam txoj kev nrog lwm yam khoom.

Qhov thib ob, cov ntsiab lus hauv tib lub sijhawm puas muaj ntau dua lossis tsawg dua li cov ntsiab lus hauv tib pawg? Cov ntsiab lus hauv tib pab pawg yog cov uas nyob hauv ib kab ntsug ntawm sab saum toj mus rau hauv qab. Lawv muaj ntau tshaj hauv feem ntau nruab nrab ntawm ob txoj kev. Lawv sib koom ib yam Tus naj npawb ntawm cov electrons hauv lawv cov valence subshells. Cov ntsiab lus nyob rau tib lub sijhawm yog cov uas nyob hauv ib kab kab rov tav los ntawm sab laug mus rau sab xis.

Ntxiv rau qhov no, vim li cas cov atoms hauv tib pab pawg muaj cov khoom qub?

Electron kev npaj thiab khoom ntawm cov ntsiab lus Yog li ntawd, cov ntsiab lus hauv tib pab pawg muaj zoo ib yam tshuaj khoom vim lawv muaj ib yam tus naj npawb ntawm cov electrons hauv lawv lub plhaub sab nraud. Cov atoms ntawm tag nrho pab pawg 1 cov ntsiab lus muaj zoo ib yam tshuaj khoom thiab cov tshuaj tiv thaiv vim lawv txhua tus muaj ib tug electron nyob rau hauv lawv lub plhaub sab nrauv.

Vim li cas cov ntsiab lus ntawm tib pab pawg muaj cov tshuaj zoo sib xws?

Cov ntsiab lus hauv tib pawg (nyob rau hauv lub periodic table) muaj cov tshuaj zoo sib xws . Qhov no yog vim lawv cov atoms muaj tus 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.
