Exploring Metals and Non-Metals
What do you already know about metals and non-metals?
Learning Objective
At the end of the lesson you will be able to identify, compare and describe properties and uses of metals and non-metals.
What Are Elements?
Elements are pure substances consisting of only one type of atom. They are arranged in the periodic table and can be metals, non-metals, or metalloids.
Properties of Metals vs Non-Metals
Non-Metals
Metals
Dull, poor conductors, brittle, can be solid, liquid, or gas, not ductile or malleable.
Shiny, good conductors of heat and electricity, malleable, ductile, mostly solid at room temperature.
Examples of Metals
Common metals include iron, copper, aluminium, gold, and silver. These are used in buildings, vehicles, wiring, and jewellery.
Examples of Non-Metals
Non-metals include oxygen, carbon, sulphur, nitrogen, and chlorine. They are found in gases, plastics, and living things.
How Do We Use Metals and Non-Metals?
Metals are essential in construction, electronics, and transport. Non-metals are vital for breathing, cleaning, fuels, and medicines.
Recap: Key Points to Remember
Metals and non-metals have distinct physical and chemical properties that determine their uses. Recognise examples of each and their everyday applications.
