Physical Properties of Metals

Some of the physical properties of metals are listed below:

• Shiny (lustrous) in nature

• Metal is a good conductor of electricity and heat

• Density and melting point is high

• Mouldable (Malleable)

• DUCTILE

• At room temperature, it is in solid form except for mercury

• Opaque

Chemical Properties of Metals

Some of the chemical properties of metals are listed below.

• Easily corrodible

• Can lose electrons

• Form basic oxides

• Have low electronegativities

• Good reducing agents

Physical Properties of Non-metals

Some of the physical properties of non-metals are listed below.

• Poor conductors of electricity and heat

• Non-Ductile metals

• Brittle solids

• Maybe solids, liquids or GASES at room temperature

• These are not SONOROUS

• Transparent

Some of the chemical properties of non-metals are listed below:

• The number of electrons in the outer shell is generally 4-8

• Easily gain or lose valence electrons

• Form ACIDIC oxides whenever they come in contact with oxygen

• High electronegative elements

• Great OXIDIZING agents

Nonmetals and metals take different forms (allotropes). They have different shapes and properties. Allotropes are elements that exist in two or more than two different physical forms.

• Example 1: A non-metal carbon – two allotropes of carbon are diamond and graphite.

• Example 2: A metal such as iron – two allotropes of iron are austenite and ferrite
