1. For each compound, draw the Lewis dot structure, the number of lone pairs, and the number of electronic groups for the central atom. Each Lewis dot structure follows the octet rule: hydrogen has one bond, all other atoms are surrounded by a total of eight electrons. Each covalent bond counts as we clectrons. Each nonbonded pair of electrons (lone pairs) count as two electrons. The number of nonbonded electrons is how many electrons from the central atom are not...
