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 good conductors of electricity?

Back

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

Front

Which of the following is NOT a property of metals?

Back

Very brittle (breaks easily)

Front

What property of metals is described by the ability to be stretched into a wire?

Back

Ductile (stretched into a wire)

Front

What is responsible for a metal being malleable, ductile, and conductive?

Back

Its sea of free-floating electrons.

Front

Define metallic bond.

Back

A metallic bond is the force of attraction between the positively charged metal ions and the sea of delocalized electrons.

Front

What is malleability in metals?

Back

Malleability is the ability of a metal to be hammered or rolled into thin sheets without breaking.

Front

What is ductility in metals?

Back

Ductility is the ability of a metal to be drawn into wires.

Front

List three properties of metals.

Back

1. Good conductors of electricity 2. Malleable 3. Ductile

Front

What is the role of valence electrons in metallic bonding?

Back

Valence electrons are the electrons that are involved in forming metallic bonds and contribute to the properties of metals.
