Having symbols for atoms of different elements allows for a simple and concise way to represent elements in chemical formulas and equations. It helps to distinguish between different elements and enables chemists to communicate effectively about the composition and reactions of chemicals.
Compounds are represented by chemical formulas, which show the types and numbers of atoms present in the compound. These formulas can be written using chemical symbols for individual elements and subscripts to indicate the number of atoms. Examples include H2O for water and CO2 for carbon dioxide.
Examples of metals with their symbols: Iron (Fe) Gold (Au) Copper (Cu) Aluminum (Al) Zinc (Zn) Examples of non-metals with their symbols: 6. Oxygen (O) 7. Nitrogen (N) 8. Carbon (C) 9. Sulfur (S) 10. Fluorine (F)
There are 5 oxygen atoms in O5. Each molecule of O5 contains 5 oxygen atoms.

Kitchen examples: wine, beer, vinegar, juice, coffee.
Chemists use chemical symbols to represent atoms or elements. These symbols are typically one or two letters derived from the name of the element in English or Latin. Examples include H for hydrogen, O for oxygen, and Na for sodium.
