Which diagram shows a metallic bond?

• 
• 
• 
• 

Which of these does NOT describe a metal bond?

• Giant structure

• Delocalised electrons and metal ions

• Electrostatic attraction

Which of these diagrams does NOT show a metallic bond?

• 
•

Metals have many bulk properties which can be explained by their metallic bonding. One of these is that the forces between the delocalised electrons and the cations is very strong resulting in the majority of metals at room temperature being solids as lots of energy is needed to break the metallic bonds.

What is the correct term for the property of metals that this gives rise to?

Metals have many bulk properties which can be explained by their metallic bonding. One of these is that the delocalised electrons are free to move and carry electrical current and thermal heat energy through the material.

What is the correct term for the property of metals that this gives rise to?

Metals have many bulk properties which can be explained by their metallic bonding. The layers of atoms in a metal slide over each other whilst still being held by the electrons. This means they can be hammered into shape.

What is the correct scientific term for this property of metals ?

Metals have many bulk properties which can be explained by their metallic bonding. The layers of atoms in a metal slide over each other whilst still being held by the electrons. This means they can be pulled into long thin wires.

What is the correct scientific term for this property of metals ?

The reactivity series lists metals in order of their reactivity with other substances. When a metal reacts a positive ion is formed and they form ionic compounds.

Which description BEST fits the metals at the top of the reactivity series?

• They lose electrons most easily forming positive ions.

• They are the least reactive

• They lose electrons forming negative ions called anions.

• They are most likely to form insoluble ionic salts

The reactivity series lists metals in order of their reactivity with other substances.

Which of the following reactions is NOT used to determine metal reactivity?

• Reaction with water

• Reaction with acids

• Reaction with other metal compounds

• Reaction with other metals
