Molecular Ionization: Is Rydberg Formula Possible?

AI Thread Summary
The discussion centers on the complexity of molecular ionization compared to the Rydberg formula, which is applicable only to hydrogen-like atoms with a single electron. While it may be possible to derive specific formulas for certain cases of molecular ionization, these would lack the fundamental significance of the Rydberg equation, often being considered mere numerology. The conversation also references Rydberg ionization spectroscopy as a related topic, highlighting the limitations of applying the Rydberg formula to more complex molecular systems.

Is there sth like rydberg formula for Molecular ionization?
 
Chemistry news on Phys.org
No, it gets more and more complicated. Rydberg formula works only for hydrogen-like atoms (nucleus and one electron).

I guess for some very specific cases similar formulas could be found, but that would be numerology - while one can find some formula for every sequence, it doesn't meant the formula touches on some deeper phenomena as it is in the case of Rydberg's equation.
 

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!!
