- koolstof - valentie en elektronische configuratie
Het atoomnummer van koolstof is 6. De elektronische configuratie is 2, 4. Het vereist:
4 elektronen om de elektronische configuratie van inert gas te bereiken.
- allotropen in koolstof-diamant en grafiet (verschil in fysische en chemische eigenschappen)
-binding in koolstof (covalnetbinding)
• koolstof heeft 4 elektronen nodig om de elektronische configuratie van inert gas te bereiken. Maar koolstof kan dat niet
vormen een ionische binding
• Het zou vier elektronen kunnen winnen die C4-kation vormen. Maar het zou moeilijk zijn voor de
kern met zes protonen om tien elektronen vast te houden.
• Het zou vier elektronen kunnen verliezen en C4+-kationen kunnen vormen. Maar er is een grote hoeveelheid voor nodig
van energie om vier elektronen te verwijderen.
• Koolstof overwint dit probleem dus door zijn valentie-elektronen te delen
andere koolstofatomen of met atomen van andere elementen.
• De binding die ontstaat door het onderling delen van elektronenparen tussen twee atomen in a
molecuul staat bekend als covalente binding
- soorten bindingen die koolstof kan vormen (enkel, dubbel)
-Lewis-structuren met voorbeelden
