Question

Write down the differences in physical properties of metals and non-metals ​

Answer 1

Explanation:

#Some 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 chemical properties of metals are listed below.

Easily corrodible

Can lose electrons

Form basic oxides

Have low electronegativities

Good reducing agents

Properties of Non-Metals

Physical Properties of Non-metals

Some 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

Chemical Properties of Non-metals

Some 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

Non-metals 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
