Here's a breakdown of what it represents:
* Chemical symbols: These are abbreviations for the elements present in the substance (e.g., H for hydrogen, O for oxygen, Na for sodium).
* Subscripts: These numbers written below and to the right of a chemical symbol indicate the number of atoms of that element in one molecule of the substance. If no subscript is written, it is assumed to be 1.
Examples:
* H₂O: This formula represents water, which is composed of two hydrogen atoms (H₂) and one oxygen atom (O).
* NaCl: This formula represents table salt, which is composed of one sodium atom (Na) and one chlorine atom (Cl).
* C₆H₁₂O₆: This formula represents glucose, a sugar composed of six carbon atoms (C₆), twelve hydrogen atoms (H₁₂), and six oxygen atoms (O₆).
Therefore, a chemical formula provides information about the types of elements present in a substance and their relative quantities.
