Metallic Bond
Metallic Bond

Metallic Bond
The Purpose of Scientists to Classify Elements
Chemists try to develop and generalize elements by classifying them according to certain characteristics.
Formation of Metallic Bond
Metal atoms are arranged closely packed and orderly in the solid state.
Valence electrons of metal atoms can be donated easily and delocalised although in the solid state.
Metal ions that are positively charged are formed when valence electrons are delocalised.
All delocalised valence electrons can move freely between the metal structure and form a sea of electrons.
Electrostatic attraction force between the sea of electrons and the positively charged metal ions forms the metallic bond as belows:
Electron Conductivity of Metals
When the electrons of metal atoms are delocalised in the sea of electrons, the metal can conduct electricity.
Electrons that move freely in the metal structure carry the charges from the negative terminal to the positive terminal when electricity is supplied.
Electrical conductivity of metals is as below:
