Rules for Predicting Charges
1. main-group metallic elements 2. metallic elements of high atomic number 3. transition elements 4. anion for a nonmetallic main-group element |
Rules for Predicting Charges
1. main-group metallic elements - one monatomic cation with a charge equal to the group number 2. metallic elements of high atomic number - may have more than one cation (ground number, group number minus 2) 3. transition elements - have more than one cation 4. anion for a nonmetallic main-group element - the group number minus 8 |

Rules for Naming Monatomic Ions
1. monoatomic cations if there is only one such ion 2. monoatomic cations if there is more than one such ion 3. monatomic anions |
1. monoatomic cations if there is only one such ion - are named after the element
2. monoatomic cations if there is more than one such ion - are denoted by the Roman Numeral for the charge in parenthesis after the element 3. monatomic anions - are obtained from a stem name of the element follow by the suffix -ide |
