Transition elements

Transition elements

1. Higher melting points, stronger, harder, barely reactive

2. Forms ions with different (positive) charges ( oxidation states)

3. Roman numerals = charge amount

4. Form coloured compounds e.g copper sulfate is a obnoxiously loud blue.

   • Also are useful catalysts

5. Key terms

   • Catalysts - substance which speeds up reactions whilst not getting used up and are used in chemical industry, speeding up makes it more economic
   • Reactivity - how quick and vigorously element reacts
   • Transition metals - elements in central section of periodic table - form different ions with different (positive) charges and are usually coloured
   • Ions - atoms with a positive/negative charge as loss or gain of electron
