Q1 In the centre of the periodic table there are blocks of  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition elements. These elements, which include  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition and copper, are known as  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition metals.
Q2 Like other metals, transition metals are  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition of heat and  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition and can easily be  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition or hammered into shape. Compared to  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition metals they have much  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition melting points (except for  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition, which is a  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition at room temperature). They are usually  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition, tough and strong. They are much  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition and so do not corrode as quickly with  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition and/or water.
Q3 These properties make transition metals very useful as  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition materials (e.g. iron, usually in the form of  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition) and for making things which must allow heat or electricity to pass through them easily (e.g.  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition for electrical cables or iron for  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition).
Most transition metals form  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition compounds. These can be seen in pottery  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition of various colours eg in weathered copper used for roofing domes, it forms a  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition basic carbonate.
Many transition metals, and their compounds, including iron and platinum, are used as  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition. The catalytic converters of car exhausts use  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition and  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition is used as the catalyst for the Haber synthesis of  alkaliammoniabentboilerscatalystscolouredconductorscopperelectricityglazesgoodgreenhardhigherironlessliquidmercurymetallicoxygenplatinumreactivesteelstructuraltransition from nitrogen and hydrogen.
