AI Thread Summary
Determining the shape of molecules involves understanding the arrangement of atoms and the angles between them, which can be influenced by factors like electrostatic forces and hybridization. For instance, the shape of water (H2O) is determined by its molecular geometry, which is a result of sp3 hybridization and the bent structure formed by the 104.45-degree angle between the hydrogen atoms. Resources like the VSEPR (Valence Shell Electron Pair Repulsion) theory and orbital hybridization concepts provide foundational knowledge for predicting molecular shapes.

How do you figure out what the shape of molecules are.

For example, Water. 1 part oxygen and 2 parts hydrogen with 104.45 degrees between the two hydrogen. That's what I want to figure out. I imagine it has something to do with the electrostatic force.

Thread 'Solubility of MgSO47H2O in water'

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...

Thread 'Why does having 8 valence electrons make an element inert?'

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!!
