The formal charge on each atom in the given species is to be determined. Concept introduction: The formal charge on an atom in a molecule or a polyatomic ion is determined from the group number of the atom and its actual valence electrons. The valence electrons are assigned on the basis of electrons shared in a covalent bond and lone pairs. If an atom bears one or more lone pairs, both the electrons in each lone pair are assigned to the atom which bears them. Each atom in a covalent bond is assigned with half of the shared electrons.

Draw a valid Lewis dot structure and determine the VSEPR molecular geometry for each central atom for each of the following. When appropriate, draw all applicable resonance structures. For species in which formal charges are not all zero, determine the nonzero formal charges on the relevant atoms.

Explaine why, in Part I, the formal charge is equal to the number of valence electrons. Match the words in the left column to the appropriate blanks in the sentences on the right. minus The formal charge on each atom is the number of valence electrons the number of plus lone pair electrons and the number of bonding electrons. The formal charge is equal to the number of valence electrons because there are bonds. one-half two times no multiple
