Crystal qauv

Cov Cesium chloride qauv adopts primitive cubic daim kab xev nrog ob lub atom hauv paus, qhov twg ob lub atoms muaj yim sib koom ua ke. Cov tshuaj chloride atoms dag rau ntawm daim kab xev cov ntsiab lus ntawm cov npoo ntawm lub voos xwmfab, thaum lub cesium atoms nyob rau hauv lub qhov nyob rau hauv nruab nrab ntawm lub cubes.

Xav txog qhov no, tus qauv ntawm cesium chloride yog dab tsi?

CsCl

Ib yam li ntawd, yog CsCl FCC lossis BCC? Nco ntsoov tias tsis muaj lattice taw tes nyob rau hauv nruab nrab ntawm lub cell, thiab CsCl tsis yog a BCC Cov qauv vim tias cov cesium ion tsis zoo ib yam rau cov chloride ion.

Xav txog qhov no, yog cesium chloride yog BCC?

Crystal qauv Daim duab 3A qhia cov cesium chloride (CsCl) qauv, uas yog ib qho kev npaj cubic. Yog hais tias tag nrho cov atoms nyob rau hauv cov qauv no yog tib hom, nws yog a bcc ua daim kab xev. Cov spheres nyob 68 feem pua ntawm cov ntim. Muaj 23 hlau nrog cov bcc ua kev npaj.

Vim li cas CsCl yog thawj zaug?

CsCl muaj ib daim ntawv cog lus ionic. For form a keeb kwm cubic lattice ob ions yuav tsum muaj qhov sib xws. Cs+ lub vojvoog yog 174 pm thiab Cl- lub vojvoog yog 181 teev tsaus ntuj yog li lawv tsim ib keeb kwm kub latt.
