Naming Ionic Compounds
Chemical reactions occur when atoms gain, lose, or share electrons.
Nonmetals gain/accept electrons. This gives them a --- charge. Negative ions are called
anions.
Metals lose/donate electrons. This gives them a + charge. Positive ions are called
cations.
Remember that the charge of an ion can be determined by its place on the Periodic
Table.
For each elements on your notes, predict the charge of its most common ion using the
periodic table.
Rules for Naming Ions
When metals lose electrons they become ions, but their name does not change.
When nonmetals gain electrons they become ions, and their name does change.
