CsCl muaj ionic daim ntawv cog lus. Yuav kom tsim ib tug primitive cubic lattice ob leeg ions yuav tsum muaj qhov loj me. Cs+ lub vojvoog yog 174 pm thiab Cl- lub vojvoog yog 181 teev tsaus ntuj yog li ntawd lawv tsim ib lub qhov cubic lattice primitive.

Ib yam li ntawd, tib neeg nug, yog cesium chloride yog ionic compound?

Cesium chloride

Yog vim li cas yog cesium chloride yooj yim cubic? CsCl muaj ib kub qauv uas muaj ib tug infinite saw ntawm ions. Lub Cs (los yog Cl) ions zaum ntawm yim lub ces kaum ntawm lub voos xwmfab thiab Cl (los yog Cs) zaum ntawm qhov chaw ntawm lub voos xwmfab (yog li nws tsis yog lub cev-hauv nruab nrab lattice vim qhov ntawd yuav tsum tau SAME ion los tuav cov npoo thiab center). CN ntawm ob qho tib si cation thiab anion yog 8.

Hais txog qhov no, qhov twg yog ionic ntau NaCl lossis CsCl?

CsCl yog ntau ionic vim Caesium (Cs) yog ntau electropositive tshaj Sodium (Na). Qhov txawv tsuas yog qhov loj ntawm cations, Cs + loj dua Na + thiab yog li Na + yuav muaj ntau polarizing zog tshaj Cs + thiab li no NaCl yuav yog ntau covalent tshaj CsCl los yog lwm yam lus CsCl yuav yog ntau ionic tshaj NaCl.

Dab tsi ntawm chav tsev cell yog CsCl?

CsCl crystallizes hauv ib kub unit cell . Qhov ntev ntawm cov chav cell ntug 0.4123nm. muaj Cl- ion ntawm lub coordinates 0, 0, 0. Muaj Cs+ ion ntawm lub coordinates 1/2, 1/2, 1/2.
