What are the main uses of non-metals?
Like metals, non-metals also play an important role in our lives. They help us in many ways. For example,
We breathe oxygen which is the basis of life of all living things including human beings. Without it, no living beings can exist alive on this earth.
Carbon dioxide which is a non-metal oxide is essential for plants to carry out photosynthesis.
Non-metals like nitrogen and phosphorus are used in fertilisers for better yield of plants. Phosphorus is used in manufacturing matchsticks and fireworks.
