Thawj qhov sib txawv ntawm hlau yog qhov yooj yim uas lawv tau txais tshuaj tiv thaiv. Cov ntsiab lus mus rau hauv qab sab laug ces kaum ntawm lub periodic rooj yog lub hlau uas yog cov nquag nquag nyob rau hauv lub siab ntawm kev ua tus feem ntau reactive. Piv txwv li, lithium, sodium, thiab poov tshuaj tag nrho react nrog dej.

Ib yam li ib tug yuav nug, dab tsi yog cov hlau nquag tshaj plaws?

Cesium

Tsis tas li ntawd, dab tsi yog qhov nquag siv tsis yog hlau? Cov feem ntau nquag siv nonmetals belongs rau lub halogen tsev neeg, uas zaum rau sab laug ntawm lub noble gases nyob rau sab xis ntawm lub periodic rooj. Cov halogens yog li reactive uas lawv yeej tsis pom nyob rau hauv lawv tus kheej. Cov ntsiab lus tshuaj fluorine , tshuaj chlorine , bromine, iodine thiab astatine ua rau halogen tsev neeg.

Hais txog qhov no, cov hlau twg muaj zog dua li hydrogen?

Kev piav qhia: Piv txwv li, tag nrho cov alkali hlau, sodium, potassium, lithium, francium, thiab lwm yam yog ntau reactive tshaj hydrogen. Ntau cov hlau hloov pauv xws li hlau, chromium, npib tsib xee, tin, zinc , thiab txhuas yog ntau reactive tshaj hydrogen.

Cov pab pawg twg muaj cov hlau nquag tshaj plaws?

Feem ntau reactive hlau nyob rau hauv periodic table Pab pawg -Kuv hlau los yog Alkali Hlau . Lawv yog cov reactive vim lawv tsim cov ions zoo tau yooj yim los ntawm kev tshem tawm ntawm cov hluav taws xob sab nraud. Thaum koj mus down Pab pawg -Kuv lawv reactivity nce thiab qhov kawg hlau Francium (Fr) yog ntseeg tias yog tus feem ntau reactive hlau nyob ntiaj teb.
