• Which metal is listed as "Highly unreactive"?

  Platinum
• Why do metals like potassium and sodium react with water?

  They are highly reactive and react violently with water
• What does the reactivity series order metals by?

  Tendency to react
• How does the reactivity of metals relate to their position in the periodic table?

  Metals become more reactive going down the periodic table groups
• Which metal is the least reactive according to the reactivity series?

  Platinum
• How can the reactivity of metals be compared?

  • Reactivity increases going down the group in the periodic table
  • Alkali metals (group 1) are the most reactive
  • Noble gases (group 18) are the least reactive
• What happens when iron is placed in copper sulfate solution?

  Iron displaces copper, forming iron sulfate
• Which metal is more reactive: potassium or gold?

  Potassium
• What is the result of a displacement reaction involving iron and copper sulfate?

  Formation of iron sulfate and copper
• Which metal is the most reactive according to the reactivity series?

  Potassium
• What action can gold perform in a displacement reaction?

  It cannot displace more reactive metals
• How do more reactive metals behave with water and acids?

  • React more vigorously
  • Produce hydrogen gas
  • Form metal hydroxides with water
• What is formed when iron displaces copper in copper sulfate?

  Iron sulfate and solid copper
• What is the analogy used to explain a displacement reaction?

  • A stronger player replaces a weaker one on a sports team
• How does a displacement reaction occur?

  A more reactive metal pushes out a less reactive metal
• What are the key features of the reactivity series?

  • Orders metals by reactivity
  • Most reactive at the top
  • Least reactive at the bottom
  • Includes hydrogen for comparison
• What are the two main reactivity properties of metals described in the image?

  • Reacts with water
  • Reacts with acids
• What is a displacement reaction?

  A reaction where a more reactive metal displaces a less reactive metal
