Cov halogens txhua tus muaj general hluav taws xob kev configuration ns2np5, muab rau lawv xya valence electrons . Lawv yog ib tug hluav taws xob luv ntawm muaj tag nrho sab nrauv s thiab p sublevels, uas ua rau lawv reactive heev. Lawv tau txais cov tshuaj tiv thaiv tshwj xeeb nrog cov reactive alkali hlau.

Tib neeg kuj nug, pes tsawg valence electrons ua alkaline ntiaj teb hlau muaj?

ob

Ib tug kuj yuav nug, dab tsi yog qhov Valency ntawm alkali hlau? Alkaline ntiaj teb hlau belongs rau pab pawg thib 2 ntawm cov lus niaj hnub niaj hnub. Lawv muaj 2 electrons nyob rau sab nraud valence plhaub. Raws li nws yooj yim rau lawv poob 2 electrons dua li nce 6 ntau electrons kom ua tiav octet, lawv poob electrons thiab tau txais tus nqi ntawm +2.

Ua kom pom qhov no, muaj pes tsawg valence electrons pom nyob rau hauv halogens?

xya valence electrons

Puas alkaline ntiaj teb hlau muaj 2 valence electrons?

Pawg 2 alkaline ntiaj teb hlau suav nrog Beryllium, Magnesium, Calcium, Barium, Strontium thiab Radium thiab yog mos, nyiaj hlau uas tsis tshua muaj hlau nyob hauv tus cwj pwm zoo li Pawg 1 Alkali hlau . Tag nrho cov cov ntsiab lus hauv pab pawg 2 muaj ob lub electrons hauv lawv valence plhaub, muab lawv lub xeev oxidation ntawm + 2.
