Kauj Ruam 4: Lub molecular geometry piav qhia txoj haujlwm nkaus xwb ntawm atomic nuclei (tsis yog ib leeg electron khub) ntawm cov molecule (lossis ion). Yog tsis muaj ib leeg electron khub ntawm lub hauv paus atom, khub electron thiab molecular geometries yog tib yam.
Yuav ua li cas molecular geometry thiab electron geometry zoo ib yam?
Linear geometry suav nrog lub hauv paus atom nrog ob khub ntawm kev sib txuas ntawm electrons ntawm lub kaum sab xis ntawm 180 degrees (ib txoj kab ncaj nraim). Qhov no tsuas yog qhov ua tau zoo rau ib kab geometry; cov electron geometry thiab molecular geometry yog tib yam.
Puas yog cov qauv molecular thiab molecular geometry tib yam?
Molecular geometry, tseem hu ua cov qauv molecular, yog tus qauv peb-dimensional lossis kev npaj ntawm atoms hauv ib lub molecule. Kev nkag siab txog cov qauv molecular ntawm cov khoom sib xyaw tuaj yeem pab txiav txim siab polarity, reactivity, theem ntawm cov teeb meem, xim, hlau nplaum, nrog rau kev ua haujlwm lom neeg.
Raws li qhov xwm txheej twg yog cov npe ntawm cov electron khub geometry thiab cov qauv molecular tib yam?
Cov electron-pair geometries yuav zoo ib yam li cov qauv molecular thaum tsis muaj ib leeg electron khub nyob ib ncig ntawm lub hauv paus atom, tab sis lawv yuav txawv thaum muaj ib khub nthuav tawm ntawm lub hauv paus atom.
Vim li cas electron geometry txawv ntawm moleculargeometry?
Electron geometry qhia peb txog kev teeb tsa ntawm pawg electron sib txawv. Molecular geometry, ntawm qhov tod tes, pab peb nkag siab tag nrho atom thiab nws txoj kev npaj. Nws yog 3D kev npaj ntawm tag nrho cov atoms nyob rau hauv ib tug tshwj xeeb molecule.
