Visual overview of non-metal applications.
From the air we breathe to the water we drink, non-metals play a crucial, life-saving role in our everyday activities.
Sulfur burning experiment and acidic non-metal oxides.
When you heat powdered sulfur, it burns to produce sulfur dioxide gas. Trapping this gas in a jar and adding water creates sulfurous acid.
This solution turns blue litmus paper red, proving that non-metal oxides are acidic in nature. This is a key difference from metals, which typically form basic oxides.
Definition of elements and everyday uses of non-metals.
Metals and non-metals are sub-categories of substances called elements. An element is a pure substance that cannot be broken down into simpler substances.
There are 118 known elements that act as the basic building blocks of all matter. Remember: complex materials like plastic, glass, and wood are not elements!
