While the four points Elements in the first 2 periods of the Periodic Table do not have access to the d sublevel and must adhere to the octet (or duet H and He) rule. angular/bent Example: H20. This is because a multiple bond has a higher electron density than a single bond, so its electrons occupy more space than those of a single bond. Top. Therefore when you cut the "xenon" plane in half you find two lone pairs either above or below the plane and then the one remaining lone pair either above/below the plane depending on where the first two lone pairs appeared.
