You made the atomic hybridization seem very easy. On the other hand MO theory especially when you went to the p-block. It was extremely abstract. It wasn't clear.

I have one more question. My book says that a bond oder of 1/2 does indicate the bond exists. For example if we have He2+ it should exist. And it indeed does in nature. So which rule should we follow? Thank you!
