Metallic Bonds

Front

What is meant by the term "sea of electrons"?

Back

It's what we call all the free floating electrons in a metal.

Front

Why are metals malleable?

Back

Even though the metal ions repel each other, the electron sea holds all the atoms in place.

Front

What property of metals allows them to conduct electricity?

Back

A negative charge can easily push the sea of electrons in one direction, making a current.

Front

What does it mean for a metal to be ductile?

Back

It means the metal can be stretched into a wire.

Front

What is the definition of metallic bonding?

Back

Metallic bonding is the attraction between metal ions and the sea of delocalized electrons.

Front

Why do metals have a shiny appearance?

Back

Metals reflect light due to the free electrons on their surface.

Front

What is the relationship between metallic bonds and electrical conductivity?

Back

The presence of free-moving electrons in metallic bonds allows metals to conduct electricity.

Front

How does the structure of metals contribute to their strength?

Back

The closely packed arrangement of metal ions and the sea of electrons provide strength and stability.

Front

What is the significance of the term 'malleability' in metals?

Back

Malleability refers to the ability of metals to be hammered or rolled into thin sheets without breaking.

Front

What is an example of a ductile metal?

Back

Copper is an example of a ductile metal that can be drawn into wires.
