Vim li cas halogens muaj tshuaj lom?

Halogens yog cov reactive heev, thiab lawv tuaj yeem tsim kev puas tsuaj lossis ua rau tuag taus rau cov kab mob lom hauv cov khoom txaus. Qhov no reactivity yog vim high electronegativity thiab high efficiency nuclear xwb. Halogens tuaj yeem tau txais ib qho hluav taws xob los ntawm kev cuam tshuam nrog atoms ntawm lwm cov ntsiab lus.
