ShowMe is an open learning community featuring interactive lessons on a variety of topics. Lewis Structures for CH4. Step-by-step tutorial for drawing the Lewis Structure for CH4. The Lewis Dot Structure for CH4 is shown above. So you would put down an O with an H on each side. Now each hydrogen only needs 2 valence electrons, so you would draw 2 dots on each side of the O, between it and the H. So you have 4 left over, so put two dots on the top, and two on the bottom. So that is the Lewis dot structure. Transcript: This is Dr. B. Let's do the Lewis structure for H2O2: Hydrogen Peroxide, also called dihydrogen dioxide.
