Enthelpy of Formation of Tetraoxygen

AI Thread Summary
The discussion centers on the Standard Enthalpy of Formation for Tetraoxygen (O4) in kJ/mol, with the original poster expressing frustration over the lack of clear information despite extensive literature. They reference the theoretical existence of two molecular forms of Tetraoxygen: a puckered ring and a pinwheel structure. The conversation highlights the challenges in obtaining empirical data due to the short-lived and rare nature of Tetraoxygen, suggesting that insufficient quantities exist for accurate measurement. Theoretical calculations are acknowledged, but the complexities involved in predicting properties of such molecules are emphasized, particularly in relation to their stability and formation.

I am curious as to what is the Standard Enthalpy Of Formation is of Tetraoxygen in kJ/mol. I am assuming reference to the molar weight of the Tetraoxygen molecule. I seem to only find papers on the subject which are abstruse with detail but no clear answer to my inquiry. I have little formal schooling in chemistry but am doing some free lance research.

Either one or both would be cool. I would down load some of the reference papers in the Wikipedia reference but currently am on a tight budget.
 
"Theoretical calculations have predicted the existence of metastable O4 molecules with two different shapes: a "puckered" square like cyclobutane or S4,[7] and a "pinwheel" with three oxygen atoms surrounding a central one in a trigonal planar formation similar to boron trifluoride.[8][9]" --- Wiki
What part of "theoretical" are you not understanding? Last time I checked, first ionization potential of He wasn't calculable from first principles; tetraoxygen has several times the number of primary particles as He.
 
Bystander, that's fine. I guess the answer to my question has been resolved. I appreciate you looking into this for me. My guess is that the tetra-oxygen is so short lived and so rare that not enough of it can be produced to do the measurements.
 

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!!
