[205957986]

what are the atoms that have octet exceptions?

[JadaArreola_2E]

The atoms that have octet exceptions are hydrogen, beryllium, or born, they do not have to reach an octet.

[Valeria Perez 3J]

The atoms that have octet exceptions that allow for less than a complete octet are the lighter s and p block elements, like Boron and Berellium. The ones that go beyond the octet are the ones that are in period 3 or beyond, because those elements have access to the d orbitals.
