Potassium yog mos, silvery-dawb hlau nrog lub melting point ntawm 63 ° C (145 ° F) thiab qhov kub ntawm 770 ° C (1, 420 ° F). Nws qhov ceev yog 0.862 grams ib cubic centimeter, tsawg tshaj li cov dej (1.00 grams ib cubic centimeter). Qhov ntawd txhais tau tias potassium hlau tuaj yeem ntab saum dej.
Ib yam li ntawd, nws raug nug, dab tsi yog 3 lub cev ntawm cov poov tshuaj?
Lub cev muaj zog ntawm Potassium yog raws li nram no:
- Xim: Nyiaj-dawb.
- Phase: Khoom.
- Melting point: Melting point ntawm 63 ° C (145 ° F) - tsawg heev rau cov hlau.
- Xim: Silvery-dawb hlau.
- Ceev: Tsawg dua dej.
Tsis tas li ntawd, lub ntsiab lus twg feem ntau yuav muaj tshuaj lom neeg zoo ib yam li cov poov tshuaj? Sodium thiab poov tshuaj qhia zoo sib xws lub cev thiab tshuaj muaj zog vim lawv nyob hauv tib tsev neeg los yog pab pawg hu ua Alkali hlau. Ob leeg yuav muaj tib valence electrons thiab lawv ob leeg heev reactive.
Ib yam li ntawd, tej zaum koj yuav nug, yam khoom twg ntawm cov poov tshuaj txaus ntshai?
| Potassium | |
|---|---|
| Electrons rau lub plhaub | 2, 8, 8, 1 |
| Lub cev muaj zog | |
| Phase ntawm STP | khov kho |
| Melting point | 336.7 K ?(63.5 ° C, ?146.3 ° F) |
Dab tsi yog siv rau cov poov tshuaj?
Kev siv loj tshaj plaws ntawm poov tshuaj yog poov tshuaj chloride (KCl) uas yog siv los ua chiv. Qhov no yog vim poov tshuaj yog ib qho tseem ceeb rau cov nroj tsuag loj hlob. Muaj kev siv rau poov tshuaj muaj xws li xab npum, tshuaj ntxuav tes, mining kub, dyes, iav ntau lawm, hmoov phom, thiab roj teeb.
