Lub cev muaj zog

Cesium yog silvery-dawb, ci iab hlau uas yog mos heev thiab ductile. Ductile txhais tau hais tias muaj peev xwm kos rau hauv cov xov hlau nyias. Nws melting point yog 28.5°C (83.3°F). Nws melts yooj yim nyob rau hauv lub tshav kub ntawm ib tug txhais tes, tab sis yuav tsum tsis txhob ua li ntawd!

Raws li txoj cai, lub cev lub cev ntawm rubidium yog dab tsi?

Lub cev muaj zog Rubidium yog mos, silvery hlau. Nws muaj ib melting point ntawm 39 ° C (102 ° F) thiab qhov kub ntawm 688 ° C (1, 270 ° F). Nws qhov ceev yog 1.532 grams ib cubic centimeter.

Tom qab ntawd, lo lus nug yog, dab tsi yog cesium ntawm lub rooj zaum? Cesium (IUPAC spelling) (tseem sau cesium hauv American English) yog tshuaj keeb nrog lub cim Cs thiab atomic naj npawb 55. Nws yog ib tug mos, silvery-golden alkali hlau nrog ib tug melting point ntawm 28.5 ° C (83.3 ° F), uas ua rau nws ib tug ntawm tsib lub ntsiab hlau uas yog kua nyob rau hauv los yog nyob ze chav tsev kub..

Ib yam li ntawd ib tug yuav nug, dab tsi yog Cesium siv rau?

Cesium yooj yim ua ke nrog oxygen thiab yog siv li ib tug getter, ib yam khoom uas sib txuas nrog thiab tshem tawm cov kab hluav taws xob los ntawm lub tshuab nqus tsev. Cesium kuj yog siv nyob rau hauv atomic moos, nyob rau hauv photoelectric hlwb thiab raws li ib tug catalyst nyob rau hauv lub hydrogenation ntawm tej yam organic tebchaw.

Cesium tuaj yeem pom qhov twg?

Qhov chaw: Cesium yog pom nyob rau hauv cov minerals pollucite thiab lepidolite. Kev lag luam, feem ntau cesium yog tsim raws li ib tug byproduct ntawm zus tau tej cov lithium hlau. Ntau tshaj li ob feem peb ntawm lub ntiaj teb reserves ntawm Cesium - 110,000 tonnes - yog pom ntawm Bernic Lake, Manitoba, Canada.
