Here's how it works:
* Elements: The chemical formula uses the element symbols (like H for hydrogen, O for oxygen, Na for sodium, etc.).
* Ratio: Subscripts (small numbers written below and to the right of the element symbol) indicate the number of atoms of each element in the compound. If there is no subscript, it implies one atom.
Examples:
* Water (H₂O): This formula indicates that water contains 2 hydrogen atoms (H₂) and 1 oxygen atom (O).
* Sodium chloride (NaCl): This formula shows one sodium atom (Na) and one chlorine atom (Cl).
* Glucose (C₆H₁₂O₆): This formula shows that glucose contains 6 carbon atoms (C₆), 12 hydrogen atoms (H₁₂), and 6 oxygen atoms (O₆).
Key points:
* Chemical formulas are a concise way to represent the composition of a compound.
* They are essential for understanding chemical reactions and the properties of compounds.
