AI Thread Summary

The discussion centers on calculating the value of I3 for lithium (Li) using the formula Z2hR/n2. The user initially set n to 3, assuming it was correct for I3, but received feedback indicating that n should actually be set to 1. The confusion arises from the application of the Rydberg formula, which is relevant to the calculation of ionization energies and spectral lines. Clarification on the appropriate value of n in this context is sought, emphasizing the importance of understanding the underlying principles of the Rydberg formula in relation to ionization states.

Hello all-

I am working to calculate the value of I₃ for Li. I am working through the formula:

Z²hR/n²

Can anyone tell me what n is equal to? I had originally set n=3 since I am looking for I₃, but it was marked incorrect as n should have been set at 1. I'm not sure why in this case

Thanks in advance.

Do you know Rydberg formula?

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 '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 '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!!
