Step 1
Which row of the table shows the typical properties of a transition metal?
Answer
The typical properties of a transition metal are that they usually have a high density and can often act as catalysts. Transition metals generally form coloured compounds, particularly their metal chlorides.
Based on the table:
- Row C states: used as a catalyst (yes), density (high), colour of metal chloride (coloured).
Therefore, the correct answer is: C.
