AI Thread Summary

The discussion centers on the comparison of filling electron orbitals, specifically the sequence of n=5 and n=6 orbitals versus n=4 orbitals. It highlights that n=4 orbitals are significantly smaller and closer to the nucleus, yet they possess higher energy than the n=5 and n=6 orbitals. This raises questions about the concept of localization in relation to these orbitals. Additionally, the conversation touches on reactivity, questioning what the n=4 orbitals are less reactive compared to, given their energy levels and size. Overall, the dialogue emphasizes the intricate relationship between orbital size, energy, and reactivity in atomic structure.

Thinking about filling sequence 5s -> 4d or 6s -> 4f, the n=4 orbitals are way smaller than n=5 or 6.

Does this mean "localized"?

Even though the n=4 orbitals are way smaller, close to nucleus, these orbitals have more energy than n=5, 6 orbitals above.

What makes it less reactive?

less reactive compared to what?

Thread 'Enthalpy - published values'

Do the published values of Enthalpy include the work done against a constant pressure, e.g., the atmosphere? (I am not a chemist). I am reviewing enthalpy and entropy as part of the statistical mechanics applied to transistors. I assume, from my reading, that the work done would mostly apply to reactions involving gasses.

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!!
