The discussion centers on the energy levels of atomic orbitals, specifically comparing the 1s and 2s orbitals. It highlights that the 1s orbital is assigned "less energy" than the 2s orbital based on both theoretical calculations and experimental measurements, with consistent results supporting this conclusion. The term "less energy" refers to the stability and energy state of electrons in these orbitals, where lower energy indicates a more stable configuration. The conversation emphasizes the reliability of both calculation and experimental data in establishing these energy levels.

can anyone tell me on what basis do we assign ok not assign conclude that 1s orbital has a "less energy" than 2s..? what do we really mean by saying less energy
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...
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.
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!!
