When filling the sides of the element symbol each side gets one dot before doubling up. Exceptions are hydrogen and helium. Example: 1s 2 2s 2 2p 4 valence electrons = 6 Prepared by Ms. Lynrie O Lewis Dot Symbol • Rules in Writing the Lewis Structure Rule #2 . No side can have more than two dots because each orbital can only hold two electrons.

    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.
