Hydrogen and oxygen are natural elements found in nature. They are both chemical elements (basic building blocks of matter).
🌬️ Oxygen (O)
Found in the air we breathe (as O₂ gas)
Also found in water, rocks, and many compounds
Plants produce oxygen through photosynthesis
🔥 Hydrogen (H)
Found in water, gases, and many compounds
It is the most abundant element in the universe
It is usually not found alone in nature; it combines with other elements
🧪 How do they form water?
When hydrogen and oxygen combine through a chemical reaction, they form water:
👉 2H₂ + O₂ → 2H₂O
Hydrogen (H₂) and Oxygen (O₂) join together
They chemically bond and create water (H₂O)
💡 Simple idea:
Hydrogen + Oxygen (from nature)
➡️ combine
➡️ form Water (H₂O)
