Cov yam ntxwv ntawm Alkali Hlau

• Pom nyob rau hauv kab 1A ntawm lub sij hawm teev.
• Muaj ib tug electron nyob rau hauv lawv txheej txheej ntawm electrons.
• Yooj yim ionized.
• Silvery, mos, thiab tsis ntom.
• Tsawg melting ntsiab lus.
• Zoo kawg nkaus reactive.

Kuj kom paub yog, peb yam khoom ntawm alkali hlau yog dab tsi?

Cov yam ntxwv ntawm alkali hlau yog:

• High reactive hlau.
• Tsis pom dawb nyob rau hauv qhov.
• Khaws nyob rau hauv ib tug ntxhia roj tov.
• Tsawg melting ntsiab lus.
• Tsawg ntom ntom (tsawg dua lwm yam hlau)
• Tsawg electronegativity.
• Tsawg ionization zog.
• React yooj yim nrog halogens.

Tsis tas li ntawd, lub cev muaj zog ntawm pawg 1 cov ntsiab lus yog dab tsi? Cov pab pawg 1 cov ntsiab lus yog tag nrho cov mos, reactive hlau nrog qis melting cov ntsiab lus . Lawv hnov mob nrog dej los tsim cov alkaline hlau hydroxide tov thiab hydrogen. Reactivity nce cov pab pawg.

Hais txog qhov no, dab tsi yog lub cev thiab tshuaj lom neeg ntawm alkali hlau?

Teb

• alkali hlau yog mos, lub teeb thiab silvery dawb hlau.
• lawv qhov ntom ntom tsawg (vim qhov loj me). nws nce mus rau hauv pawg.
• Lub melting thiab boiling cov ntsiab lus ntawm alkali hlau yog tsawg vim tsis muaj zog hlau bonding vim muaj ib tug electron nyob rau hauv valance plhaub.

Vim li cas cov hlau alkali muaj cov khoom zoo sib xws?

Alkali hlau muaj cov khoom zoo sib xws vim lawv nyob hauv ib yam Pab pawg (Pab 1). Qhov no txhais tau tias lawv yuav muaj tus ib yam tus naj npawb ntawm valency electrons nyob rau hauv lawv lub plhaub sab nraud. Txawm hais tias qhov reactivity nce rau pawg 1 vim tias nws yooj yim dua rau cov atoms poob lawv cov electrons.
