Giant Ionic, Metals and Alloys

What type of elements are present in an ionic structure

• Metal and a non-metal

• Metal atoms only

• Non-metal atoms only

• Carbon

Which is NOT a property of ionic structures

• High melting point

• Conduct electricity when solid

• Conduct electricity when dissolved

• Conduct electricity when molten

Why do ionic structures have a high melting point

• Strong electrostatic attraction between oppositely charged ions

• Strong covalent bonds

• Strong ionic bonds

• Electrostatic attraction between atoms

Which of these is NOT present in an ionic structure

• Positive metal ion

• Negative non metal ion

• delocalised electrons

• electrostatic attraction

Use your Periodic Table to determine the ion charge on a Sodium ion

• Na+

• Na-

• S2+

• S2-

What is the ionic formula for Magnesium Oxide

• Mg₂O₂

• MgO

• MgO₂

• Mg₂O

What word describes how metals can change shape when hit with a force

• Malleable

• Conductor

• Hard

• Strong

Why can't ionic structures conduct electricity as a solid

• There are no charged particles

• Delocalised (free) electrons are unable to move

• The charged ions are fixed in place

• The ions are arranged in layers

Which of these is NOT present in a metallic structure

• Delocalised (free) electrons

• Positive Ions

• Negative Ions

• Electrostatic Attraction

Which of these is NOT a property of metals

• Malleable

• High Melting Point

• High electrical conductivity

• Low thermal conductivity
