Metals and Non-
Metals
Introduction to Metals and 
Non-metals
Elements Classification
Elements are classified 
into metals, non-metals, 
and metalloids based on 
their physical and 
chemical properties.
Metals in Our Lives
Metals like iron, aluminum, 
and copper are used in 
everyday objects from 
utensils to buildings due to 
their strength and 
conductivity.
Non-metals Matter
Non-metals such as oxygen, carbon, and sulfur are essential 
for life processes and are found in air, water, and living 
organisms.

Properties of Materials
Identification
Properties help us 
identify and 
classify materials 
as metals or non-
metals.
Characteristics
We examine 
appearance, 
hardness, and 
ability to conduct 
heat and 
electricity.
Classification
These properties allow us to group materials 
into distinct categories.
