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.
