Metallic Bonding

Front

What is metallic bonding?

Back

Metallic bonding is the electrostatic attraction between positively charged metal ions and the 'sea' of delocalized electrons that surround them.

Front

Why do metals form metallic bonds?

Back

Metals form metallic bonds because they 'want' to give up their valence electrons, allowing them to achieve a stable electron configuration.

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, which contribute to the conductivity and malleability of metals.

Front

What is a characteristic property of metals due to metallic bonding?

Back

Metals are malleable, meaning they can be shaped into thin sheets without breaking.

Front

What is an alloy?

Back

An alloy is a mixture of two or more elements, where at least one is a metal, designed to enhance certain properties.

Front

Is brass an alloy of iron and copper?

Back

False. Brass is an alloy of copper and zinc.

Front

What type of ions are present in metallic bonding?

Back

Cations (positively charged metal ions) are present in metallic bonding.

Front

What is the role of delocalized electrons in metallic bonding?

Back

Delocalized electrons allow metals to conduct electricity and heat, as they can move freely throughout the metal.

Front

How does metallic bonding affect the boiling and melting points of metals?

Back

Metals typically have high boiling and melting points due to the strong attraction between cations and the sea of electrons.

Front

What is ductility in metals?

Back

Ductility is the ability of a metal to be drawn into wires without breaking, a property resulting from metallic bonding.
