: hydrogen

: bromine

: nitrogen

: idelium

Metal-Strong

-Malleable and ductile

-High melting and boiling points

-Good conductor of heat

-Shiny when polish

-React with oxygen to form basic oxides

CHARACTERISTIC

Non-Metal-React with oxygen to form acidic oxides

-Dull sound when hit with hammer

-Low melting and boiling point

-Poor condustors of electricity

-Dull looking

-Low density

Ferrous• From Latin word = ‘Contain iron’

• Use in large quantity

• Include pure iron

• Wrought iron

• Alloy ( steel )

• Magnetic

• Non-magnetic is stainless steels

Non-ferrous• Non-magnetic

• Cobalt and nickel are exceptions

CATEGORIES OF METAL

Base Metal• zinc,

• Reacting with an acid

• Use to refer to a metal

• Oxidizes or Corrodes relatively easily

• React variably with

• Dilute hydrochloric acid ( HCI ) to form Hydrogen

• Example : iron,nickel,lead

Noble Metal• Resistance to corrosion or oxidation

• Perceived rarity

• Examples :

• Gold

• Platinium

• Silver

• Rhodium

Precious Metal• Rare melallic chemical element of high economic value

• Less reactive

• High important as currency

• Is a Gold and Silver

• Include platinium group metal:

• Ruthenuim,Rhodium,Palladium,Osmium,Iridium.

Iron• Used for strength application

• Wrought iron contain

• less then 0.2% carbon

• Cast iron between 2-4% carbon

• Iron with a carbon content between 0.2-2% is classified as steel.

Iron

Examples of Iron

Cooking panTraditional equipments

Aluminium• Is a alloy

• Easy to form

• Readily available

• Inexpensive

• Recyclable

Aluminium

Examples of Aluminium

Laptop Drinking Can Laptop’s Cover

Copper• Have a number of properties that make them useful

• Include :

• High electrical

• Thermal conductivity

• High ductility

• Good corrosion resistance

Copper

Copper Coil

Copper Spring

Titanium• Alloy

• Strength in higher temperature ( ~1000’ F ) application

• When component weight is a concern

Titanium

Titanium Alloy

Titanium Rods

Nickel• Alloy

• Use for higher temperature ( ~1500-2000’ F ).

• When good corrosion resistance is required.

Nickel

Coin

Nickel Titanium Alloy

METAL- Made into jewellery due to their hard and shiny appearance

-Used to make pans due to good conductor of heat

-Malleable,ductile and good conductor of electricity and used in electrical cables

USES OF METAL AND NON-METAL

NON – METAL-Used as insulating material around wire cables since they do not conduct electricity

-Used to make pans handles as they are poor of conductors of heat
