Octet Rule

In what scenario is it okay to break the octet rule?

I do not know all the exceptions but elements containing d-orbitals can hold more electrons than the octet rule.
P can hold up to 10 electrons.
S can hold up to 12 electrons.
B, Al- 6 electrons.

I believe starting at the d orbitals, this rule no longer applies because these elements can hold more than 8 electrons (same with p and f). I think the TA's also explained it as the elements on the 3rd row or lower that break this rule, so you can see it like that on a test.

It's ok to break the octet rule when:
1. there are an odd number of valence electrons
2. there are too few valence electrons
3. there are too many valence electrons
It lays it out nicely here! https://chem.libretexts.org/Core/Physic ... Octet_Rule
