Ionic Compounds
Names and Formulas of Ionic Compounds
Compounds formed from charged ions are electrically neutral. Therefore, equations must be balanced so that the total charges of the formula are neutral.
Naming Ionic Compounds
Metal + Non-Metal
Magnesium + Chlorine
Magnesium chloride
The first part of a name refers to the metal ion in the compound and the second part to the non-metal. The non-metal also has its ending changed to "ide"
Properties of Ionic Compounds
Hard, brittle, solid. Often electrolytes.
Electrolytes
A compound that separates into ions when it dissolves in water, producing a solution that conducts electricity
The simultaneous strong attraction of positive and negative ions in an ionic compound
A compound made up of one or more positive metal ions and one or more negative non-metal ions
The simultaneous strong attraction of positive and negative ions in an ionic compound
Naming Ions
Polyatomic Ions
An ion made up of more than one atom that acts as a single particle
Cations
A negatively charged ion
Ions
A positively charged ion
Definition
