Transition Metals

• Where can transition metals be found in the periodic table?


  Between Group 2 and Group 3
• What is the general location of transition metals in the periodic table?


  In the centre of the periodic table
• What are the typical properties of transition metals?


  They are good conductors of heat and electricity, dense, strong, and shiny
• What are some special properties of transition metals?


  • Can have more than one ion (e.g., Cu⁺ and Cu²⁺)
  • Often coloured ions, leading to colourful compounds (e.g., potassium chromate(VI) is yellow)
  • Often act as good catalysts (e.g., nickel in hydrogenation, iron in Haber process)
• Give an example of a transition metal that forms multiple ions.


  Copper
• What ions can copper form?

  Cu⁺ and Cu²⁺
• What ions can cobalt form?


  Co²⁺ and Co³⁺
• Why are transition metal compounds often colourful?


  Because transition metal ions are often coloured
• What is an example of a colourful transition metal compound?


  Potassium chromate(VI)
• What colour is potassium chromate(VI)?


  Yellow
• What is another example of a colourful transition metal compound?


  Potassium(VII) manganate
• What colour is potassium(VII) manganate?


  Purple
• What role do transition metals often play in chemical reactions?


  • They often act as good catalysts
  • Speed up the rate of reactions
  • Examples include:
  • Nickel in hydrogenation of alkenes
  • Iron in the Haber process for ammonia
• What catalyst is used in the hydrogenation of alkenes?


  Nickel
• What catalyst is used in the Haber process for making ammonia?


  Iron
• How do metals and non-metals differ in properties?

  Metals are typically good conductors and dense, while non-metals are not
• What is a common phrase used to describe the difference between metals and non-metals?


  Like chalk and cheese
• What is the significance of the phrase "I hope there's no metal in your cheese" in the context of metals and non-metals?


  It emphasizes the distinct differences between metals and non-metals
• What are transition metals known for in terms of their catalytic properties?


  They are good catalysts.
• Where are transition metals located in the periodic table?


  In one center of the periodic table.
• What is an example of a transition metal that acts as a catalyst in the Haber process?


  Iron (Fe).
• How do transition metals affect the rate of reaction in chemical processes?


  They speed up the rate of reaction without being used up.
• What color are Fe ions?


  Green.
• What color are Cu²⁺ ions?


  Blue.
• What are some examples of transition metals?


  • Chromium (Cr)
  • Manganese (Mn)
  • Iron (Fe)
  • Cobalt (Co)
  • Nickel (Ni)
  • Copper (Cu)
• What are the general properties of transition metals?


  • Dense
  • Shiny
  • Strong
  • Good conductors of heat and electricity
• How do transition metals compare to Group I elements in terms of melting points?


  Transition metals have higher melting points than Group I elements.
• How do transition metals compare to Group I elements in terms of reactivity?


  Transition metals are less reactive than Group I metals.
• What is a characteristic of Group I metals regarding the formation of ions?


  Group I metals do not form more than one ion.
• What is a characteristic of transition metals regarding ion formation?

  Transition metals can form more than one ion.
