- The chemical formula for water is H₂O.
What does H₂O mean?
- H stands for hydrogen.
- O stands for oxygen.
- The small number 2 means there are two hydrogen atoms.
So, H₂O means that one water molecule is made up of:
- 2 hydrogen atoms
- 1 oxygen atom
These atoms are chemically bonded together.
How is water formed?
- When two hydrogen atoms combine with one oxygen atom through a chemical reaction, they form a molecule of water. This process also releases energy and creates a stable substance that is essential for life.
Why is water important?
- Water is vital for all living things.
- It helps in digestion, circulation, temperature control, and many other body processes.
- It is also essential in plants for photosynthesis and transporting nutrients.
Summary:
- The chemical formula for water is H₂O, which means it contains two hydrogen atoms and one oxygen atom. This simple molecule is essential for life on Earth.
