Unformatted text preview: interact with each other by changing the number of their electrons so as to acquire the structure (become isoelectronic with) a noble gas. With the exception of helium, 1s2 = 2, each noble gas has 8 electrons with an s2p6 distribution in its highest principal energy level." BEWARE! The Octet Rule is a useful generalization for determining valence but should not be followed slavishly. O2 represents an exception to the octet rule generalization. (This exception occurs pursuant to a more fundamental empirical rule of quantum mechanics, Hund's Rule. Hund's Rule states: "electrons remain unpaired with parallel spins in orbitals of equal energy until each such orb...
