Carbon Compounds: Orbital & Bonding Energies Explained

AI Thread Summary
Carbon can form polymers due to its ability to create stable, strong covalent bonds with itself, resulting in long chains that serve as backbones for various polymer structures. This capability is attributed to carbon's tetrahedral bonding geometry and optimal orbital hybridization, allowing for diverse bonding configurations. In contrast, silicon, despite being tetravalent, has larger atomic size and lower bond energies, which leads to weaker Si-Si bonds. While silicon can form polymers, such as silicones, these structures typically involve oxygen atoms connecting silicon atoms rather than direct Si-Si linkages. This distinction highlights the fundamental differences in the polymerization behavior of carbon and silicon.

why carbon can form polymers and sillicon not? though both are tetra valent. explain this based on its orbital and bonding energies

Are you sure there are no silicon polymers? (Hint: look up silicones)
 
In silicones Si atoms are not directly connected, they are connected through oxygen atoms - while carbon chains are a backbone of many carbon based polymers. I guess that's what the question aims at.
 
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
