C2.6 - THE TRANSITION ELEMENTS

C2.6 - THE TRANSITION ELEMENTS

1. TRANSITION ELEMENTS AND THEIR COMPOUNDS ARE IMPORTANT INDUSTRIAL CATALYSTS

2. A TRANSITION ELEMENT CAN FORM IONS WITH DIFFERENT CHARGES, IN COMPOUNDS THAT ARE OFTEN COLOURED

3. THE TRANSITIION ELEMENTS DO NOT REACT VIGOROUSLY WITH OXYGEN AND WATER

4. COMPARED WITH THE ALKALI METALS, TRANSITION ELEMENTS HAVE MUCH HIGHER MELTING POINTS AND DENSITIES . THEY ARE ALSO STRONGER AND HARDER BUT ARE MUCH LESS REACTIVE

5. PHYSICAL PROPERTIES:

   • GOOD CONDUCTORS OF ELECTRICITY/THERMAL ENERGY
   • HARD + STRONG
   • HIGH DENSITIES
   • HIGH MELTING POINTS (EXCEPT MERCURY)
