    Shell Stability
AI Thread Summary
Atoms exhibit higher stability with a full valence shell due to the principles of electron configuration and energy minimization. A full valence shell leads to lower potential energy and increased stability, as atoms strive for a state of minimal energy. This stability is influenced by electromagnetic forces, particularly the attraction between positively charged nuclei and negatively charged electrons. The tendency of atoms to achieve a full valence shell is also explained by the octet rule, which states that atoms are most stable when they have eight electrons in their outer shell. The discussion highlights the importance of understanding these fundamental forces and principles in atomic behavior.

Hello,
I am wondering about the real explanation that atoms have a tendency to have higher stablity with a full valence shell. What forces are at work here besides the 'happy' atom.

Is this the wrong area for this thread or something else?
 
You already asked the same question and received a detailed response
 
Yeah, but I asked here first and for some reason, it was not an appropriate question for this area, I suppose. That is why I asked the question in the other area.
 
Let the discussion proceed in the other forum.
 
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...
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!!
