Chemical Nomenclature  is the systematic naming of chemical compounds. Here we examine just a few rules  for chemical substances that can be named relatively easily. 1. Name the cation (the more electropositive one) first and the anion (the more electronegative one)  second. 2. Monoatomic cations take their name from the element name. 3. Monoatomic anions take their names from the first part of the element name and then add  "-ide" Cation Name H + Hydrogen Na + Sodium Al 3+ Aluminum Anion Name H - Hydride Cl - Chloride O 2- Oxide 4. What are the names for  NaCl MgO , and  HBr ? 5. NaCl  = sodium chloride 6. MgO  = magnesium oxide 7. HBr  = hydrogen bromide 8. When elements form more than one type of ionic compound Roman numerals are used to indicate the  charge on the cation. Fe 2+ and O 2- give FeO = Iron(II) Oxide Fe 3+ and O 2- give Fe 2 O 3 = Iron(III) Oxide Sn 2+ and Cl - give SnCl 2 = Tin(II) Chloride
