Why is a full valence shell more stable?

[scott_alexsk]

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

 

[scott_alexsk]

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.
