an element that is a metal plus an element that is a non-metal. These compounds are ALWAYS ionic bonds.

does that help?

An ionic bond is formed from a metal and non-metal. This kind of bond is electrostatic meaning it forms from elements having different charges. Because metals easily take a charge they are always found in ionic bonds.

Guys, the key part of the phrase here is "elements" this means a pure substance and won't include things like phosphates or carbonates. Ionic bonds will form between any two elements which result in a full outer shell of electrons in both elements. The most obvious example are Group 1 and Group 18 on the periodic table: http://upload.wikimedia.org/wikipedia/commons/a/a8/Periodic_Table_of_Elements_showing_Electron_Shells.svg
