1. Nomenclature
Unit 6 - Bonding

2. Types of Ions Monatomic = 1 atom Names
Representative elements TYPICALLY have only one possible charge
Names
Cations = name of the element
Ca2+ = Calcium ion
Anions = remove ending, add “–ide”
N3- = Nitride

3. These Transition Metals only have ONE charge!!!
Types of Ions
Transition metals and some representative elements have more than one charge.
There are two ways to name these elements…
Fe2+, Fe3+
Cu+, Cu2+
Sn2+, Sn4+
Pb2+, Pb4+
These Transition Metals only have ONE charge!!!
Ag+
Zn2+

4. Types of Ions Stock System Latin System
Element name with charge in parentheses (Roman Numerals)
Copper (I) = Cu+
Latin System
Latin root + suffix
- ous = Lower charge
- ic = Higher charge
Ferric and Ferrous

5. Types of Ions Polyatomic Ions = A charged GROUP of bonded atoms
Acts as ONE UNIT in an ionic bond
Cations: Only NH4+
Anions: More common as polyatomics
Look at the back of the periodic table!!

6. Naming Ionic Compounds
Cation is always named first (No # prefixes)
Cation  take the name of the element
Transition metals  use the anion to find the charge of the cation
(Roman numeral = charge)
Anion
Monatomic  end in –ide
Polyatomic  name from chart
