they represent the number of protons and electrons.
The little numbers next to the letters in a formula of a molecule represent the number of atoms of that element present in that molecule. They should be written as subscripts.
It stands for the amout of atoms there are, for example Co2 means one Carbon atom and two oxygen atoms.

A molecular formula shows the numbers and kinds of atoms in a molecule but not the arrangement of the atoms.

A molecular formula shows the types and numbers of atoms in a molecule, but not the bonds. A structural formula shows the way in which the atoms bond.
The molecular formula for a water molecule tells you the numbers and kinds of atoms in a molecule. For example, the formula H2O means that one molecule of water contains two hydrogen atoms and one oxygen atom.
The lowered numbers are called subscripts, and represent either the number of atoms of the element they follow in a molecular formula, or the ratio of ions in an ionic compound. For example, the molecular formula for a water molecule, H2O, indicates that there are two hydrogen atoms and one oxygen atom per molecule. Also, the formula unit for the ionic compound calcium chloride, CaCl2, indicates that in the ionic compound, the ratio of calcium ions to chloride ions is 1 to 2.
It is algebra that uses letters to represent numbers and also Roman numerals.
They can represent values in cells. They also can represent columns (letters) and rows (numbers).
The molecular formula shows the numbers and types of atoms in a molecule, but not how they are bonded. The structural formula shows how the atoms are bonded.
Literal numbers are the letters which are used to represent a number.
A molecular formula shows the numbers and kinds of atoms in a molecule but not the arrangement of the atoms.
No, they do not. Although it is using letters to represent numbers, Roman numbers are fixed symbols, unlike letters in algebra which represent variables.
A molecular formula contains the atomic composition by element and their quantities. For example H2O is the molecular formula for water. The formula indicates that there are two atoms of hydrogen (H) and one oxygen (O) in each water molecule. Through the molecular formula molar mass can further be derived. In the case of water is 18-grams per mole.
represent the letters with numbers
There are many different systems of using numbers to represent letters. Binary is commonly used.
How about: VI-I-MMXIII which are letters that represent numbers
