When you are finished drawing your 2D structure, click on the Get Lewis Dot Structure button to see the result.. At this point, all the Fluorines have 8 valence electrons, so their octets are full, but the Arsenic has 2, 4, 6, 8, 10 valence electrons. By clicking the link, you can find the extra book to read. All elements in groups 1,2,13,14,15,16,17, and 18 … So CH4 is the only combination that works…. A Lewis dot structure is a drawing of a molecule. So it’s a nice tool to explore how atoms bond into more complex substances. When several dot structures are reasonable for a molecule or ion, they all contribute to the molecular or ionic structure making it more stable. Each bond (stick) represents a pair of valence electrons, and the pairs of dots also represent pairs of valence electrons. 28 - 6 = 22. I was just wondering how to do AsBr5 because if you bond 5 Br's to As then As will have 10 electrons which doesn't make sense O_O.
