VSEPR Theory - not homework related

AI Thread Summary
The discussion centers on the concept of electron pair repulsion in molecular geometry, specifically when there are five or more electron pairs. It emphasizes that repulsion between electron pairs can be neglected when the angle between them exceeds 90 degrees. This suggests that in such configurations, the dominant interactions are between pairs that are closer together, typically at angles less than 90 degrees. The implication is that understanding these angles is crucial for predicting the shapes of molecules, as the arrangement of electron pairs influences molecular geometry significantly.

When there are 5 or more electrons pairs neglect repulsion between electron pairs at an angle greater than 900

This is an excerpt from http://www.s-cool.co.uk/alevel/chemistry/atomic-structure/shapes-of-molecules.html" SCROLL DOWN.

My question is quite simple : what does this mean ? What are they trying to say ?

Perhaps that system is dominated by repulsions of pairs with angles lower than 90°?
 

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!!
