Lewis structures

Exercise 5


Draw Lewis structures of complex molecules or ions from inorganic chemistry: - First the central atom is drawn with its neutral Lewis structure: - Each unpaired electron: one bond (often with O or S ) - The lone pairs of the central atom may form dative covalent (dipolar, coordinate) bonds - Each dative bond increases the charge of the central atom by one unit and diminishes the charge of the bonded atom by one unit.

Find the Lewis structure (with formal charges) of:
