Transition Metals

• What are transition elements?

  They are metals located between groups 2 and 3 of the periodic table.
• What are some physical properties of transition elements?

  They have high melting points, high densities, and are strong and hard.
• What do transition elements form?

  They form coloured compounds.
• How do transition elements act in chemical reactions?

  They act as catalysts.
• What are the typical physical properties shared by transition elements and other metals?

  • Conduct electricity in solid and liquid states
  • Shiny appearance when freshly cut
• How do the melting points of transition metals compare to those of group 1 metals?

  Most transition metals have higher melting points than group 1 metals.
• What is the significance of the central part of the periodic table?

  • Contains transition elements
  • Located between groups 2 and 3
• Name 6 main types of transition metals:


  Chromium, Cr

  Maganese, Mn

  Iron, Fe

  Cobalt, Co

  Nickel, Ni

  Copper, Cu
• Why are transition metals denser than Group 1 metals?

  Transition metals are denser because they have heavier atoms and closely packed structures.
• How do transition metals compare to Group 1 metals in terms of strength and hardness?

  Transition metals are generally stronger and harder than Group 1 metals.
• How do Group 1 metals react with oxygen compared to transition metals?

  Group 1 metals react quickly with oxygen, while transition metals react more slowly.
• What is the difference in reactivity with water between Group 1 metals and transition metals?

  Group 1 metals react explosively with water, but transition metals react much less.
• How do Group 1 metals and transition metals differ in their reactivity with halogens?

  Group 1 metals form ionic halides easily, while transition metals can form covalent compounds and vary in reactivity.
• What are the differences in properties between transition metals and Group 1 metals?

  • Melting point: Transition metals have relatively high melting points; Group 1 metals have relatively low melting points.
  • Density: Transition metals have relatively high density; Group 1 metals have relatively low density.
  • Strength: Transition metals are relatively strong; Group 1 metals are relatively weak.
  • Hardness: Transition metals are relatively hard; Group 1 metals are relatively soft.
  • Reactivity: Transition metals react slowly or not at all; Group 1 metals react easily.
• What is a typical property of transition elements regarding their ions?

  They have ions with different charges.
• What is the reactivity of transition metals with oxygen, water, and halogens?

  Transition metals react slowly or not at all.
