Cov khoom ntawm kev hloov pauv muaj xws li:

• muaj tus nqi loj / vojvoog piv;
• yog cov tawv thiab muaj siab ceev;
• muaj siab melting thiab boiling ntsiab lus;
• daim ntawv sib txuas uas feem ntau yog paramagnetic;
• qhia qhov sib txawv ntawm oxidation xeev;
• tsim xim ions thiab cov tebchaw;
• tsim cov tebchaw nrog kev ua haujlwm catalytic;

Tsis tas li lo lus nug yog, qhov twg yog cov yam ntxwv ntawm kev hloov pauv cov ntsiab lus?

Variable Valency, tsim cov tebchaw hauv ntau lub xeev oxidation sib txawv. Cov xim sib txawv, tsim cov xim sib txawv. Catalytic khoom , kev hloov hlau yuav ua tau zoo heev catalysts. Lub cev khoom , kev hloov hlau muaj siab melting thiab boiling ntsiab lus raws li high densities.

Ib yam li ntawd, vim li cas cov hlau hloov pauv tau siv tau? Hloov cov hlau yog siv raws li catalysts nyob rau hauv ntau txoj kev. Peb siv hlau nto nrog oxides los ua ammonia. Qhov no yog txoj kev pheej yig tshaj plaws los tsim cov ammonia, thiab siv ntau hauv cov chiv. Cov hlau nto tuaj yeem adsorb cov ntsiab lus thiab compounds rau hauv nws tus kheej.

Ntawm no, dab tsi yog lub cev lub cev ntawm kev hloov pauv lub ntsiab lus qhia?

Cov Hloov cov ntsiab lus yog hlau . Lawv muaj cov ntsiab lus melting siab thiab ntom, thiab yog muaj zog thiab nyuaj. Lawv tsim cov xim sib xyaw ua ke thiab ua raws li catalysts.

Vim li cas halogens thiaj li reactive?

Halogens yog heev reactive , thiab lawv tuaj yeem tsim kev puas tsuaj lossis ua rau tuag taus rau cov kab mob lom hauv qhov ntau 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. Fluorine yog ib qho ntawm feem ntau reactive cov ntsiab lus.
