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.

Cov alkali hlau thiab alkaline ntiaj teb hlau sib txawv li cas?
Valance: Tag nrho cov alkali hlau muaj ib qho hluav taws xob nyob rau hauv lawv lub plhaub sab nraud thiab tag nrho cov alkaline ntiaj teb hlau muaj ob sab electrons. Txhawm rau kom ua tiav qhov kev teeb tsa tsis zoo, cov hlau alkali yuav tsum poob ib lub tshuab hluav taws xob (valence yog "ib"), thaum alkaline ntiaj teb hlau yuav tsum tshem tawm ob lub electrons (valence yog "ob")
Muaj pes tsawg valence electrons nyob rau hauv nruab nrab atom ntawm astatin?
Xya valence electrons
Muaj pes tsawg valence electrons muaj nyob rau hauv lithium?
Lithium muaj 3 electrons --- 2 hauv thawj lub plhaub, thiab 1 hauv lub plhaub thib ob (yog li ib qho hluav taws xob valence)
Muaj pes tsawg lub roob hluav taws uas muaj nyob hauv ntiaj teb 2019?
2019: Xyoo nyob rau hauv Volcanic Activity. Tawm ntawm kwv yees li 1,500 lub roob hluav taws kub hauv ntiaj teb, 50 los yog li ntawd tawg txhua txhua xyoo, spewing chav, tshauv, pa phem, thiab lava
Puas yog alkali hlau thiab alkaline ntiaj teb hlau zoo ib yam?
Valance: Tag nrho cov alkali hlau muaj ib qho hluav taws xob nyob rau hauv lawv lub plhaub sab nraud thiab tag nrho cov alkaline ntiaj teb hlau muaj ob sab electrons. Yuav kom ua tiav cov kev teeb tsa muaj txiaj ntsig zoo, cov hlau alkali yuav tsum poob ib lub tshuab hluav taws xob (valence yog "ib"), thaum alkaline ntiaj teb hlau yuav tsum tshem tawm ob lub electrons (valence yog "ob")
