Energy in lewis structures

[404768057]

How can you tell which structure has higher or lower energy? For example in 3.54, we have to identify which structure has the lowest energy.

[Savanna Gharibian 1A]

I believe you can tell which one has the lowest energy by looking at the formal charges of each atom in the structure. I think the one with the lowest charges should be the one with lower energy.

[Savanna Gharibian 1A]

And also, do you mean problem 3.53?

[904571591]

When the formal charge is 0, then the energy is the lowest.
