1.) Summarize the octet rule. Atoms have a tendency to lose, gain, or share electrons such that their (______________) valence shell or core shell results in an octet of electrons. In other words, atoms have a tendency to lose, gain, or share electrons so as to achieve the (_______________) stable or unstable electronic configuration of the (___________) inert metal or noble gas or reactive gas or reactive metal . 2.) Using the VSEPR model,
