INTRODUCTION

As scientists discovered elements there was a need to classify them. Thus elements were classified  based on their properties.

Try to list from the periodic table some of the elements that are familiar to you.

Hydrogen

Iron

Gold

Are there metals in this list? Which are they?

PROPERTIES OF METALS

1. Malleability

2. Ductility

3. Hardness

4. Metallic luster

5. Good conductors

6. Sonarity

MALLEABILITY

Metals can be beaten into thin sheets by hammering. This property is known as malleability.

Try to find instances where malleability of metals are employed

Aluminium foil used to wrap chocolates.

DUCTILITY
Metals can be drawn into thin wires.This property is known as ductility.

The filaments of electric bulbs are made of fine wires of Tungsten. Tungsten can be drawn into thin wires. Hence it is used to make the filament.

Platinum is the most ductile metal.

HARDNESS OF METALS

Hardness is another property of metals.

Eg.Copper, Aluminium ,Iron.

But there are few metals which are soft.

Eg. Sodium, Gallium,Cesium, Lithium, Potassium
