Metals are good conductors of electricity and heat, have high melting and boiling points, and can be hammered into shapes or pulled into wires. Examples include aluminum, copper, iron, and silver. Non-metals include gases like oxygen and neon at room temperature, liquids like bromine, and solids like carbon and phosphorus. Unlike metals, non-metals do not conduct electricity well and have low melting and boiling points.

1. METALS AND NON METALS

2. METALS
• Metals are elements that are good conductors of electricity
• Metals are distinguished from other elements by their unique physical and chemical properties.
• Examples of metals include
1 Aluminium
2 Copper
3 Iron
4 Calcium
5 Platinum
6 Silver
7 Gold
8 Magnesium
9 Sodium
10 Lead

3. CHARACTERISTICS OF METALS
• Metals are very good electrical conductors
• Metals are very good heat conductors
• Metals have a high boiling point
• Metals have a very low melting point
• Metals are malleable ( they can be hit into different shapes
• They are ductile (they can be pulled into thin wires
• They are sonorous (they produce sound when they hit the ground)
• They shine when cut

4. NON METALS
Non metals can be grouped into 3 categories
(Gaseous non metals)
These are substances that are gases at room temperature and pressure (rtp)
Examples include
1 Oxygen
2 Hydrogen
3 Fluorine
4 Neon
5 Xenon
6 Chlorine

5. NON METALS
Liquid non metals
Some non metals are liquid at rtp
Examples of liquid non metals include
1 Bromine
2 Galium
Solid non metals
Some non metals are solids at rtp
Examples include
1 Diamond (carbon)
2 Phosphorous
3 Sulfur
4 Silicon
5 Iodine

6. NON METALS
• Characteristics of non metals
1 They do not conduct electricity
2 They are poor conductors of heat
3 They have a very low melting and boiling point
4 They are nun ductile
5 They are non malleable
6 They are not sonorous.
