Metallic Bonds

Front

What is a metallic bond?

Back

A metallic bond is a bond between metal atoms where electrons are shared in a 'sea' of delocalized electrons, allowing for conductivity and malleability.

Front

What property of metals allows them to be stretched into wires?

Back

Ductility - the ability of metals to be stretched into wires without breaking.

Front

What is the term for metals being able to bend without breaking?

Back

Malleability - the ability of metals to be shaped or bent without breaking.

Front

Why are metals good conductors of electricity?

Back

Because a negative charge can easily push the sea of electrons in one direction, creating an electric current.

Front

What is the 'sea of electrons' in metallic bonding?

Back

The 'sea of electrons' refers to the delocalized electrons that are free to move around, allowing metals to conduct electricity.

Front

What is the significance of the metallic bond in terms of metal properties?

Back

Metallic bonds give metals their characteristic properties such as conductivity, malleability, ductility, and luster.

Front

How does the structure of metals contribute to their conductivity?

Back

The structure allows electrons to move freely, facilitating the flow of electric current.

Front

What happens to metal ions when a metal is deformed?

Back

Metal ions can slide past each other due to the presence of the electron sea, allowing the metal to deform without breaking.

Front

What is the relationship between metallic bonds and the luster of metals?

Back

The delocalized electrons can absorb and re-emit light, giving metals their shiny appearance.

Front

What is an example of a metal that is highly ductile?

Back

Copper - it can be drawn into thin wires.
