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,

3.) What is the difference between sigma and pi bonds? You only have one attempt at this question.

Circle the correct answer! Choose only 1.

sigma bonds are the overlap of s-orbitals

sigma bonds are the overlap of both s- and p-orbitals     

pi bonds are the overlap of both s- and p-orbitals

pi bonds are the overlap of p-orbitals
