WebAug 14, 2024 · Oxygen (atomic number 8) has a pair of electrons in any one of the 2 p orbitals (the electrons have opposite spins) and a single electron in each of the other two. Fluorine (atomic number 9) has only one 2 p orbital containing an unpaired electron. WebLet us determine the Lewis structures of SiH 4, CHO 2 −, NO +, and OF 2 as examples in following this procedure: Determine the total number of valence (outer shell) electrons in the molecule or ion. For a molecule, we add the number of valence electrons on each atom in the molecule: SiH 4 Si: 4 valence electrons/atom × 1 atom = 4 + H: 1 ...
