level questions: Transition Metals
| Question | Answer |
|---|---|
| What are the physical properties of transition metals? | - they conduct electricity in the solid and liquid states - they are shiny when freshly cut Compare to other metals, most transition metals have: - higher melting points - higher densities - greater strength - greater hardness |
| How do the transition metals react with oxygen compared to group 1 elements | - Group 1 metals react quick with oxygen at room temp - Most transition elements react slowly, or not at all, with oxygen at room temperature (some require heat to react with oxygen) |
| How do the transition metals react with water compared to group 1 elements | REACTION WITH COLD WATER - Group 1 elements: vigorously - Most transition metals: slowly or not at all |
| How do the transition metals react with halogens compared to group 1 elements | - Group 1 elements: vigorously - Some transition metals react with halogens |
| Describe the colour of compounds of transition and 'normal' metals | - Metals: usually form white compounds - Transition elements: form coloured compounds |
| What are catalysts (give 2 examples)? | Substances that increase the rate of reaction without being used up in the reaction: - iron: the catalyst in the Haber process, which makes ammonia - manganese(IV) oxide increases the decomposition of hydrogen peroxide to oxygen and water |
