C2.6 - The Transition elements.

Question 1

Physical properties of transition elements

Answer 1

• good conductors of heat/electricity
• hard and strong
• high density
• high melting points (except mercury which is a liquid)

Question 2

Chemical properties of transition elements

Answer 2

• much less reactive than alkali metals
• do not react as easily with oxygen/water than alkali metals do
• only reacts with other elements in the correct conditions

Question 3

Reactions of the transition elements

Answer 3

• always form positive ions

- always form different coloured compounds

Question 4

Why do they form different coloured compounds

Answer 4

due to the different charges of the metal ions in the compound

Question 5

pale green

Question 7

chromium (III) oxide colour of compound

Answer 7

dark green

Question 8

manganese (II) chloride colour of compound

Answer 8

pale pink
