Metallic Bonding Concepts

Front

What is metallic bonding?

Back

Metallic bonding is the electrostatic attraction between positively charged metal ions and a sea of delocalized electrons that are free to move throughout the structure.

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

How do alloys differ from pure metals?

Back

Alloys can have different properties than pure metals, often being stronger, more resistant to corrosion, or having improved ductility.

Front

What is ductility?

Back

Ductility is the ability of a material to be stretched into a wire without breaking.

Front

What is malleability?

Back

Malleability is the ability of a material to be hammered or pressed into shape without breaking.

Front

Why are metals good conductors of electricity?

Back

Metals are good conductors of electricity because they have a sea of delocalized electrons that can move freely, allowing electric current to flow.

Front

What does it mean for a metal to be hard?

Back

A metal is considered hard if it has a strong metallic bond, which is due to the sea of electrons tightly holding the metal ions together.

Front

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

Back

The 'sea of electrons' allows metals to conduct electricity and heat, and contributes to their malleability and ductility.

Front

What is the relationship between metallic bonding and the physical properties of metals?

Back

The strength of metallic bonding influences the physical properties of metals, such as hardness, melting point, and conductivity.

Front

What is the effect of temperature on the properties of metals?

Back

As temperature increases, metals can become more malleable and ductile, but may also lose strength.
