Select three which are properties of metals.

• Can conduct electricity and heat

• Ductile

• Low melting points

• Flaky

• Malleable

Metals are malleable, what does this mean?

• They can be bent or dented

• They can be pulled into long and thin wires

• They heat up quickly

• They can be taken apart

Metals are ductile, what does this mean?

• They can be bent or dented

• They can be pulled into long and thin wires

• They heat up quickly

• They can be taken apart

Metals are malleable because the metal ion are arrange in ____ which can slide over each other.

Metals can be pulled into long thin wires, when this happens the ions move closer together but they do not repel eachother because the delocalised electrons can move between the ions and s______ them form each other.

I can hit a metal with a hammer without the metal shattering because of its __________.

• Ductility
• Malleability
• Conductivity
• Lustrousness
