L11 - Metals vs. non-metals

A long chain of smaller, repeating molecules bonded together.

• Repeat unit

• Polymer

• Ion

• Monomer

Electrons that are not attached to a particular atom.

E.g. in a metal, outer electrons can be free to move through the solid.

• Loose

• Independent

• Delocalised

• Disconnected

The regular arrangement of ions in an ionic substance.

• Ionic lattice

• Ionic pattern

• Ionic bonding

• Ionic material

Allows heat or electricity to go through

• insulator

• conductor

• luster

• ductile

Usually electrons or ions, which move through a substance as electricity.

• Chargers

• Charged particles

• Electroballs

• Electric carriers

Which of these pictures shows the particles in a solid, pure metal?

• 
• 
• 
• 

Brass is an alloy made of

• copper and zinc

• copper and tin

• copper and nickel

• copper and aluminium

Atoms in metals are arranged in layers that can slide over each other. This makes them...

• dense

• conductive

• easy to bend and shape

• shiny

Most metals contain delocalised electrons, which can move freely through their structure. What does this allow the metal to do?

• Look shiny

• Bend more easily

• Melt at a higher temperature

• Conduct electricity
