Metals and non-metals - JSS1 Basic science Lesson Note

Metals and non-metals are two categories of elements based on their properties:

 

Metals:

Metals are typically shiny, malleable, and ductile.

They conduct heat and electricity well.

They tend to lose electrons in chemical reactions, forming positive ions.

Examples include iron, copper, aluminum, and gold.

 

Non-metals:

Non-metals are generally dull, brittle, and poor conductors of heat and electricity.

They usually gain electrons in chemical reactions, forming negative ions.

Examples include carbon, oxygen, sulfur, and nitrogen.

This classification helps us understand the fundamental properties and behavior of different elements, aiding in various scientific and practical applications, such as in industry, chemistry, and materials science.
