Chemistry worksheet for practicing Lewis structures and valence electron calculations.
A chemistry worksheet titled "Chem 1020 Lewis structures worksheet" with a table to complete for elements H, C, N, O, and F/Cl/Br/I, listing their group, valence electrons, and normal number of covalent bonds. Below, there are ten neutral molecules listed for which the total number of valence electrons should be calculated and Lewis structures drawn, including F₂, O₂, N₂, CH₄, CH₃Cl, CH₂Cl₂, COCl₂, HCN, NOBr, and C₂H₂.
