The Transition elements Transition Elements

  3. Identifying Some Transition Metal Ions. Method:- We added sodium hydroxide to eight solutions labelled A to H to identify the Cu2+, Fe2+ and Fe3+ solutions.Results:-

  4. Balanced Ion Equations. Cu2+ + 2OH- Cu(OH)2Fe2+ + 2OH- Fe(OH)2Fe3+ + 3OH- Fe(OH)3

  5. The three most commonly known transition elements are iron or steel, copper and zinc. iron or steel copper zinc Electrical and plumbing work General engineering metal Galvanising steel to protect it Uses (continued)

  6. Pair the metal catalyst with the substance. Fe Ni Ti V A B C D

  7. Pair the statement about the transition elements with the words.

  8. Pair the metal up with its uses copper iron or steel zinc A B C

  9. Which is a true statement about most transition elements? They are non-metals. They are light (low density). They are strong. They are non-conductors.

  10. Which of these does copper NOT tend to be used for? Plumbing work. Electrical work Ornaments and jewellery Tools

  11. Transition elements can speed up other reactions without getting used up in the process. What do we call substances that do this? Capitalists Catalysts Catholics Catapults

  12. Transition elements often form coloured compounds. What colour compound does copper usually form? Blue Yellow Red Violet

  13. How would you describe the reactivity of transition elements within the Periodic Table? Always more reactive across periods (left to right). Generally less reactive across periods (left to right). No change in reactivity. Changes but no trends in reactivity.
