A chemical formula is a shorthand notation that represents the elements present in a compound along with the number of atoms of each element. It uses chemical symbols and subscripts to convey this information in a concise manner.
The subscripts in a chemical formula indicate the number of atoms of each element present in the compound. They show the ratio of the different elements in the compound's composition.

Chemical formulas are made of symbols representing elements and subscripts indicating the number of atoms of each element in a molecule.
A chemical formula is a combination of symbols that shows the ratio of elements in a compound. Each element is represented by its chemical symbol, and the subscripts indicate the relative number of atoms of each element in the compound.
In the formula for a compound, you will see atomic symbols representing individual elements, and if needed, you will see subscripts that represent the number of those atoms required for that bonding scenario. Sodium chloride, for example is NaCl. You see the symbol for sodium followed by the symbol for chlorine. No subscripts are needed because sodium and chlorine combine in a 1-1 ratio. However, in aluminum oxide, the formula is Al2O3. Two aluminums are required for every three oxygens. The subscripts reflect that bonding ratio.
A shorthand notation that represents a compound or diatomic molecule is called a chemical formula. This notation uses symbols for the elements involved and subscripts to indicate the number of atoms of each element in the molecule. For diatomic molecules, such as oxygen (O₂) or nitrogen (N₂), the subscript "2" denotes that two atoms of the same element are bonded together. For compounds, like water (H₂O), the formula shows the ratio of different elements in the molecule.
It use the symbols as alphabetical characters for element names for examples: C for Carbon, Cu for copper (Cuprum in latin)And in the lower left of the symbol is atomic number, for C it is 6: 6Cin the upper left of the symbol is the mass number, for C it is 12 : 12C(or with another isotope, 13)Then the full nomination: 612C (write 6, and 12 one column aligned)(answer)My chemistry book states that its a Chemical Formula, "a shorthand representation of the composition of a substance using atomic symbols and numerical subscripts"
The chemical formula of a compound provides information about the elements present in the compound and the ratio in which they are combined. The subscripts in the chemical formula indicate the relative number of atoms of each element in a compound.
Chemical symbols for compounds are written by combining the chemical symbols of the elements in the compound, along with subscripts to indicate the number of atoms of each element present. For example, water (H2O) is composed of two hydrogen atoms and one oxygen atom. The chemical symbols are always listed with the element that appears first in the compound listed first.

Sure! Here is an example of an ingredient list for water, using atomic symbols and subscripts: H2O
