4.1.1 The reactivity series

• The least reactive metal in the reactivity series is gold
• Gold is highly resistant to corrosion
• The reactivity of metals is influenced by their ionization energy.


  True
• In the reaction $K +$$CuSO_{4} \rightarrow K_{2}SO_{4} +$$Cu$, potassium displaces copper
• Silver is less reactive than copper
• A more reactive metal can displace a less reactive metal from its compounds


  True
• Arrange the following metals in order of decreasing reactivity:

  1️⃣ Potassium

  2️⃣ Sodium

  3️⃣ Calcium

  4️⃣ Magnesium

  5️⃣ Aluminum
• A more reactive metal cannot displace a less reactive metal from its compound

  False
• A larger atomic radius increases metal reactivity


  True
• Copper can displace zinc from zinc sulfate

  False
• During the reaction of zinc with copper sulfate, zinc dissolves and copper precipitates

  True
• The reactivity series is a list of metals arranged in order of their reactivity
• The main metals in the reactivity series are arranged based on their ability to displace each other.

  True
• A more reactive metal can displace a less reactive metal from its compounds.


  True
• Metals with lower ionization energies are more reactive
• Copper can displace potassium from potassium sulfate.

  False
• What is the reactivity series based on?

  Metal reactivity
• Which metal is the least reactive in the reactivity series?

  Gold
• What does the reactivity series rank metals based on?

  Displacement ability
• What is ionization energy related to metal reactivity?

  Electron removal
• What type of reactions does the reactivity series predict?

  Displacement
• What happens in a displacement reaction?

  One metal replaces another
• What does the reactivity series allow us to predict in chemical reactions?

  Metal displacement
• The reactivity series is constructed by observing displacement reactions

  True
• Zinc reacts with acids to produce hydrogen gas.


  True
• Arrange the following metals in order of decreasing reactivity:

  1️⃣ Calcium (Ca)

  2️⃣ Magnesium (Mg)

  3️⃣ Aluminum (Al)

  4️⃣ Zinc (Zn)

  5️⃣ Iron (Fe)
• Potassium can displace copper from copper sulfate.

  True
• Arrange the following metals in order of decreasing reactivity:

  1️⃣ Calcium (Ca)

  2️⃣ Magnesium (Mg)

  3️⃣ Aluminum (Al)

  4️⃣ Zinc (Zn)

  5️⃣ Iron (Fe)
• The reactivity series arranges metals from most to least reactive
• The reactivity series is used to predict displacement reactions between metals


  True
• The main metals in the reactivity series are potassium, sodium, calcium, magnesium, aluminum, zinc, iron, lead, copper, silver, and gold
• Low ionization energy means higher reactivity.
• The reactivity series predicts that a more reactive metal can displace a less reactive metal from its compounds
• In displacement reactions, a more reactive metal pushes a less reactive metal out of its salt
• Zinc can displace copper from copper sulfate
