LiBr Lithium bromine ide Metal (cation) first - name stays the same How do we name ionic compounds? Metal (cation) first - name stays the same Non-metal (anion) second - drop the ending and add –ide LiBr Lithium bromine ide

Transition metals can have different charges Ions of Transition Metals Transition metals can have different charges

Form ionic compounds just like the other ions Ions of Transition Metals Form ionic compounds just like the other ions

BUT! The naming is different. Ions of Transition Metals BUT! The naming is different.

How would this ionic compound be named? Al2O3 Ions of Transition Metals How would this ionic compound be named? Al2O3 Aluminum oxide

Ions of Transition Metals After writing the name of the element, you put a roman numeral in parentheses to show the charge. (for most)

So for this, it wouldn’t just be iron bromide. Ions of Transition Metals So for this, it wouldn’t just be iron bromide. Iron has a charge of 3+, it would be named iron (III) bromide.

Ions with more than one atom. The whole molecule has that charge. Polyatomic ions Ions with more than one atom. The whole molecule has that charge.

Example: Sulfate (SO42-) There are sulfur and oxygen atoms in this ion Polyatomic ions Example: Sulfate (SO42-) There are sulfur and oxygen atoms in this ion And the whole ion has a charge of 2-.

They combine in compounds the same way. Need to use parentheses. Forming Ionic Compounds They combine in compounds the same way. Need to use parentheses.

The name is just the name of the ion. Forming Ionic Compounds The name is just the name of the ion. Aluminum nitrate The names of the polyatomic ions are on Table 9.3 from pg. 257.
