Chapter 9.6 - An Introduction to Metallic Bonding

What does the electron-sea model propose?

That metal atoms pool their electrons together in a sea of electrons

Are the metal ions orderly or disorganized in metallic bonding?

Orderly

How many atoms in metallic bonding share electrons?

All of them

Does metallic bonding form compounds or alloys?

Alloys

What is an alloy?

An alloy is a combination of metals in a substance

What are the 2 features of the electron-sea model that explain metallic properties?

The order of the metal ion array and the number and mobility of the valence electrons

How many metals are solids?

Nearly all

Do metals have high, moderate, or low melting points?

Moderate to high

Do metals have high, moderate, or low boiling points?

High

How does the melting points of metallic bonds relate to atomic size

Inversely proportional

Why does metal dent or bend?

The metal cations won’t collide with each other but instead will shift past each other into new positions

Are group 11 metals soft and malleable or hard and brittle?

Soft and malleable

What is special about gold when it comes to its physical properties?

It is extremely malleable and ductile, more than any other metal

Are metals good conductors of electricity in water, outside of water, or both?

Both

Why are metals good conductors of heat?

Because of their freely moving electrons
