### How are octet-rule models supported by thermodynamics and quantum theory? [closed]

I understand that the four quantum numbers dictate how many electrons can "fit in a shell," but I don't understand how gaining a full octet is particularly energetically favorable. The example of ...

### Why do acid base reactions cause the reacting or forming molecules to accelerate? (Basically, why do acid base reactions produce heat?) [duplicate]

My question is hopefully pretty clear, but to rephrase my question: Why do acid base reactions produce heat? We know that heat is merely the transference of momentum (or velocity) between molecules. ...
Having to retake an introductory chemistry course has gotten me thinking. Covalent bonding is where electrons are shared between two atoms that both want more electrons. Let us take $\ce{O2}$ as an ...
