This document summarizes the properties and uses of transition metals. Transition metals make up blocks of 30 elements in the middle of the periodic table. They are typically hard, tough metals with high melting and boiling points. They are good conductors of heat and electricity. Common transition metals include copper, iron, gold, and mercury. Copper is used for wiring due to its conductivity. Iron is used to make steel for its strength. Gold is used in jewelry for its malleability and color. Mercury is used in thermometers due to its liquid state at room temperature.

2. TRANSITION ELEMENTS
• TRANSITION ELEMENTS ARE BLOCKS OF 30
ELEMENTS IN THE MIDDLE OF THE PERIODIC TABLE.
THEY ALL ARE MRTALS AND INCLUDE MOST OF THE
METALS EHICH WE USE IN OUR DAILY
LIFE.REACTIVITY INCREASES DOWN THE GROUP.

3. PHYSICAL PROPERTIES
• HARD,TOUGH
• HIGH MELTING & BOILING POINT EXCEPT MERCURY.
• MALLEABLE & DUCTILE
• GOOD CONDUCTORS OF HEAT & ELECTRICITY
• HIGH DENSITY
MERCURY GOLD RHODIUM IRIDIUM

4. CHEMICAL PROPERTIES
• THEY ARE MUCH MORE REACTIVE THAN THE METALS OF GROUP 1.
• LOW REACTIVITY THAT MEANS THAT THEY DONOT CORRODE READILY
WITH AIR AND WATER EXCEPT IRON.
• THEY SHOW NO CLEAR TREND IN THEIR REACTIVITYUNLIKE GROUP 1
METALS.
• MOST TRANSITION FORM COLOURED COMPOUNDS.
COPPER SULFATE ZINC SULFATE IRON SULFATE

5. USES OF TRANSITION METALS
• GOLD FOR JEWELLERY
• COPPER FOR WIRING
• IRON FOR STEEL
• MERCURY IN THERMOMETER

6. GOLD
• GOLD IS A TRANSITION METAL WHICH IS
YELLOW IN COLOUR AND IS MALLEABLE AND
DUCTILE. IT IS USED IN MAKING ORNAMENTS
AND JEWELLERY. IT IS OFTEN MIXED WITH
ALLOY TO STRENGHTEN IT.

7. COPPER
• COPPER IS A VERY GOOD CONDUCTOR OF
ELECTRICITY AND IS. DUE TO ITS THIS
PROPERTY IT IS USED IN WIRES.

8. IRON
• IRON IS A VERY STRONG BUT CHEAP METAL
AND DUE TO ITS THIS PROPERTY IT CAN EASILY
BE SHAPED INTO PIPES AND CAN BE USED FOR
INDUSTRIAL PURPOSES.

9. MERCURY
• MERCURY IS THE ONLY METAL IN THE LIQUID
STATE. IT HAS A HIGH MELTING POINT AND SO
IT CAN BE USED IN THE THERMOMETERS.
