Catenation yog lub peev xwm ntawm lub atom los tsim cov ntawv cog lus nrog lwm cov atoms ntawm tib lub caij. Nws tau nthuav tawm los ntawm ob qho tib si carbon thiab silicon.
Vim li cas carbon qhia catenation Tab sis silicon tsis?
Vim li cas silicon tsis muaj peev xwm ntawm tib yam ntawm catenation li carbon? Thesilicon atom yog loj dua cov carbonatom, nws covalent vojvoog yog 111 pmcarbon yog 77 teev tsaus ntuj uas ua rau nws nyuaj dua rau silicon los tsim tetrahedral kev npaj nrog lwm cov atoms. Daim ntawv cog lus Si-Si tseem ntev dua thiab tsis muaj zog dua li C-C daim ntawv cog lus.
Cov ntsiab lus twg tuaj yeem ua rau pom kev?
Cov piv txwv feem ntau ntawm catenation lossis cov ntsiab lus uas nthuav tawm catenation yog:
- Carbon.
- Silicon.
- Sulfur.
- Boron.
Puas boron qhia catenation?
Apart from carbon, lwm cov ntsiab lus muaj peev xwm ntawm catenation muaj xws li, silicon, sulfur, boron, phosphorous, thiab lwm yam. Txawm li cas los xij, tsis muaj ib qho ntawm cov ntsiab lus no ntev npaum li cov saw hlau li carbon.
Qhov twg ntawm cov ntsiab lus hauv qab no tsis tuaj yeem qhia cov cuab yeej ntawm catenation?
Catenation is not shown by lead. Los ntawm pawg neeg hlau ua cim nce thiab Pb yog hlau thiab catenetion yog cov khoom tsis yog hlau.
