Transition metals

Transition metals

1. Hard

   • tools

2. dense

3. Less reactive

   • doesnt react with oxygen or water- can be used for many things- more useful

4. Different ions

   • different ions usually form different colored compounds too
     • Fe 2+ = green Fe 3+ = red/brown

5. Shiny

   • decorative items

6. Used as a catalyst

   • Iron- Haber process- speed up reaction on making ammonia
   • Nickel- oils into fats or making margarine

7. Colored compounds

   • colors in gemstones' sapphires and emeralds and pottery glazes all from transition metals

8. good conductors of heat and electricity

   • used in cirbuits

9. High melting and boiling points

   • except for mercury- liquid at room temperature
