Txhua halides ntawm Be yog covalent thiab electron tsis txaus. Vim li no, lawv tsis ruaj khov. Yog li, txhawm rau kom muaj kev ruaj ntseg lawv polymerise ua cov saw ntev. Lawv ua qhov no los ntawm kev tsim cov ntawv cog lus sib koom ua ke (dative covalent bonds) ntawm ib leeg khub ntawm halide atoms thiab cov atoms beryllium uas nyob ib sab.
Vim li cas cov hydrides ntawm Be polymerize?
Beryllium chloride yog ib qho hluav taws xob tsis muaj hluav taws xob vim Be tsuas muaj ob daim ntawv cog lus thiab yog li tsuas yog plaub lub tshuab hluav taws xob hauv lub plhaub valence. Yog li, beryllium chloride muaj cov qauv polymeric vim nws cov hluav taws xob tsis txaus. …
Vim li cas beryllium polymerize hydrogen halides?
Hydrides thiab halides ntawm \(Be) tsuas muaj plaub electrons nyob rau hauv lub plhaub valence yog li, lawv yog electron tsis muaj molecules. Vim li no, lawv tsis ruaj khov. Yog li ntawd, txhawm rau kom muaj kev ruaj ntseg lawv polymerise ua cov saw ntev.
Puas beryllium tsim polymeric hydrides?
Cov hydrides ntawm beryllium thiab magnesium yog covalent thiab polymeric (BeH2)n. muaj cov saw hlau uas muaj cov saw hlau nrog cov txuas txuas nrog hydrogen ntawm beryllium atoms Txhua beryllium atom yog sib txuas rau ob lub atom hydrogen thiab txhua hydrogen atom rau ob beryllium atoms.
Puas yog beryllium halides electron tsis txaus?
Lub halides ntawm beryllium yog electron deficient thiab yog polymeric nrog halogen txuas hniav.
