CHEMISTRY 1111 Name: Date: NOMENCLATURE LABORATORY Part A: The IUPAC nomenclature for inorganic compounds is divided into three main categories. List the three main categories is the spaces below: a) b) c) Part B: Naming Monoatomic Cations: Groups I and 2, and the aluminum (Al), zinc (Zn), and Silver (Ag) cations are named for the parent metal followed by the word "ion". Example: Al is called Aluminum ion. Other metals (like transition metals) often form more than one cation so...
