A numeral (number) written as a subscript following the chemical symbol will tell you how many atoms of that element are in the molecule being discussed. Let's take sulfuric acid as an example. It's H2SO4 as the chemist or student of chemistry writes it. There is a "sub2" following the H, so there are 2 atoms of hydrogen. There is no subscript after the S so there is only a single atom of sulfur; it's understood to be a 1 so we don't have to write it. The "sub4" after the O tells us there are 4 atoms of oxygen in this compound. Simple and easy.
Each compound is represented in a chemical formula by using symbols to represent the elements present and subscripts to indicate the ratio of each element in the compound. For example, water is represented by the chemical formula H2O, where "H" represents hydrogen and "O" represents oxygen, and the subscript "2" indicates that there are two hydrogen atoms for every one oxygen atom in the compound.
Each compound is represented as the elements it contains in one molecule. For example, salt, or sodium chloride, is written as NaCl, because each molecule has one sodium atom and one chlorine atom. Carbon Dioxide is similarly written as CO2 because every molecule has one C (carbon) atom and two O (oxygen) atoms.

A chemical compound is represented by what?
A chemical compound is represented by a specific combination of chemical elements bonded together in a specific ratio. This combination is represented by a chemical formula that shows the type and number of atoms of each element in the compound.
What is the definition on a combination of symbols that show ratio of elements in a compound?
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.
Why mixtures don't have chemical formula while compound have chemical formula?
Because as a rule only a chemical compound has a chemical formula; a mixture contain two or many componds and each compound has a different chemical formula.
What does a chemical compound formula tell you?
It tells what elements are present in a molecule and how many atoms of each element are present.
What chemical formula includes the of each element in the compound?
You think probable to chemical symbols.

How are chemical represented?
Chemicals are represented by their chemical formula, which is a combination of symbols representing the elements present in the compound and the number of atoms of each element in the compound. Chemical structures, such as line diagrams or molecular models, can also be used to represent the arrangement of atoms and bonds in a chemical compound.

Because as a rule only a chemical compound has a chemical formula; a mixture contain two or many componds and each compound has a different chemical formula.
What is the number of each type of element in a compound?
The number of each type of element in a compound is determined by the subscript in the chemical formula. Subscripts indicate the ratio of each element present in the compound. By counting the number of atoms represented by each element, you can determine the quantities of elements in the compound.
Why is the chemical symbol of a molecule of a compound also called the chemical formula of the compound?
The chemical symbol of a molecule represents the individual elements present in the compound, while the chemical formula shows the ratio of each element in the compound. The formula is essentially a written expression of the molecule's composition and structure, making it equivalent to the symbol in chemical representation.
How does the chemical formula of a compound relate to the relative number of atoms in the compound?
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.
What does a chemical compound formula tell you?
It tells what elements are present in a molecule and how many atoms of each element are present.
What is a symbol that shows the elements in a compound and the ratio of atoms?
You think probable to the chemical formula of a molecule.
What chemical formula includes the of each element in the compound?
You think probable to chemical symbols.
How do you build a compound from the chemical formula?
To build a compound from a chemical formula, first identify the elements present in the formula. Then, determine the ratio of each element in the compound. After that, use this information to arrange the atoms in the correct structure following the rules of chemical bonding.
What is a combination of symbols and numbers that describes a molecule?
A combination of chemical symbols that show what elements make up a compound and the number of atoms of each element in the smallest unit of the compound is a chemical formula.
