ionic compound

Ions are formed when atoms lose or electrons. bonding happens between a and a non-metal atom. This involves a transfer of from one atom to another. Atoms which lose electrons become charged. Atoms which gain electrons become charged.

Compounds form regular structures in the solid state. They form a large of ions. The overall charge on an ionic compound is , since the total number of positive ions is to the total number of negative ions.

Examples of ionic compounds are Sodium Chloride, Magnesium Oxide, and Calcium Chloride. Ionic compounds are solids , and they have high and boiling points. They are usually in water and insoluble in solvents. They also conduct when they are melted or dissolved in water.
