The Octet (Eight Electron) Rule  Applies to atoms of the representative elements of the s and p  blocks (Groups 1, 2, 13-18).  Each atom in a molecule seeks to achieve an s 2 p 6  valence shell  electronic configuration, through    electron transfer, leading to ionic bonding.    electron sharing, leading to covalent bonding.  Exceptions to the rule include    H - achieves a stable s 2  configuration.    Be - achieves a stable s 2 p 2  configuration, as in BeH 2 .    B - achieves a stable s 2 p 4  configuration, as in BF 3 .    Nonmetals in period 3 and above possessing d orbitals       and capable of  valence shell expansion .

Constructing Lewis Structures  of Simple Covalent Substances Step 1: Identify the central and terminal atoms.  Step 2: Sum the number of valence electrons of all atoms.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
