usually a subscript denotes the number of atoms of a particular element within the formula. ie H2O (the 2 would be a subscript) indicates there are two atoms of hydrogen in one molecule of water.
The subscript in a chemical formula refers to the _____.
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
There is one atom of that element in the molecule.

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.
In a chemical formula, a subscript is a number written to the right and slightly below the symbol for the chemical element. If the subscript is 1, it is not written. The subscripts for the chemical formula for water, H2O, are 2 for hydrogen and 1 for oxygen. The subscripts for the chemical formula for glucose, C6H12O6, are 6 for carbon, 12 for hydrogen, and 6 for oxygen.
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
The chemical formula of dichlorine monoxide is Cl2O - 2 is a subscript.
1
How does a subscript affect the element just before it?
The chemical formula for the oxygen in the air is O2, where the 2 should be a subscript.
