- The transition elements
- The transition elements are found in the periodic table between groups 2 and 3.
- They are all metal and so are sometimes called the transition metals
- Except for mercury, they have higher melting and boiling points than the alkali metals.
- They are all malleable and ductile and they are good conductor of heat and electricity
- The react only slowly, or not at all, with oxygen and water at normal temperatures.
- Most are strong and dense and are useful building materials, often as alloys
- They form positive ions with various charges, e.g. Fe2+ and Fe3+.
- Compounds of the transition metals are often brightly coloured.
- Many transistion metals and their compounds are catalysts for chemical reactions
- The charge on a transition metal ion is given by the Roman numeral after its name. e.g. iron(II) chloride contains Fe2+ ions and so its formula is FeCl2.
