These worksheets are meant to test what a student knows about metallic bonding. Suitable for: Grade 8, Grade 9, Grade 10, Grade 11, Grade 12.

Metallic bonding is the electromagnetic interaction between loosely held, delocalized, valence electrons, gathered in an "electron sea", and the metallic nuclei.

The strength of ionic bonding in different compounds can be compared by using the amount of energy required to separate the ions.
