Stable forms for Standard Enthalpies of Formation

Must we memorize the stable form of every element in order to conclude that their Standard Enthalpies of Formation is zero?

I think that Dr. Lavelle was hinting at the fact that the stable form of every element should be known because he was talking about how oxygen's stable form is O2 gas and he went over other elements as a review. So in that case, I would say yes, you should memorize, it'll make things easier.

I wouldn't say EVERY element. But I would definitely pay attention to those that he discusses in lecture or some that may pop up in the HW problems.
