Cov s - thaiv cov ntsiab lus muaj xws li hydrogen (H), helium (He), lithium (Li), beryllium (Be), sodium (Na), magnesium (Mg), potassium (K), calcium (Ca), rubidium (Rb), strontium (Sr), cesium (Cs), barium (Ba), francium (Fr) thiab radium (Ra). Daim ntawv teev caij nyoog qhia raws nraim qhov twg cov no cov ntsiab lus yog nyob rau hauv lub s - thaiv.

Tsis tas li cov lus nug yog, muaj pes tsawg lub ntsiab lus nyob hauv ib qho thaiv?

14 yam

Ib sab saum toj no, vim li cas S thaiv cov ntsiab lus yog cov hlau mos? s - thaiv cov ntsiab lus kuj hu ua cov hlau mos vim s - thaiv muaj hlau uas yog li ntawd mos thiab lub teeb uas lawv tuaj yeem txiav tau yooj yim los ntawm riam. Piv txwv li, lithium, sodium, potassium. Qhov no softness nce hauv pawg thiab hlau kawg qhov kawg ntawm pab pawg kuj tuaj yeem tawg yam tsis muaj riam.

Hais txog qhov no, S block yog dab tsi?

Cov s - thaiv yog ib tug ntawm plaub thaiv ntawm cov ntsiab lus nyob rau hauv daim ntawv periodic. Lub ntsiab ntawm s - pab pawg muaj vaj huam sib luag. Cov electron nyob rau hauv lawv feem ntau sab nraud electron plhaub yog nyob rau hauv lub s - orbital. Cov ntsiab lus hauv s - yog nyob rau hauv thawj ob lub sij hawm lub rooj pawg. Cov ntsiab lus hauv ib pab pawg hu ua alkali hlau.

Vim li cas S thaiv cov ntsiab lus muaj zog heev?

s - thaiv cov ntsiab lus muaj ib los yog ob lub electron nyob rau hauv lawv cov e shells, li no lawv ua ruaj khov los ntawm muab ib tug electron yooj yim (tsawg ionization zog) los ua singly them zoo ions, i.e. cations. Yog li ntawd lawv yog heev reactive thiab yuav tsum muaj tsawg kawg nkaus ntawm lub zog rau lawv cov kev xav.
