They tell you how often an atom - or a group of atoms - are repeated.
The chemical formula for ammonia is NH3.
The chemical formula for ammonia is NH3.
The subscript in a chemical formula represents the amount of that atom in that compound's formula.

subscript
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
subscript
A symbol with no subscript has an implicit subscript of 1, meaning one atom of that element per formula unit. I'm not quite sure that's what you were asking.
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
The chemical formula for ammonia is NH3.
The chemical formula for ammonia is NH3.
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.
The subscript is mentioned only in a chemical formula.3 FeCl3 in a chemical reaction is not similar to Fe3O4 in a chemical formula.
